If a histogram reader waits for completion in the do_histogram ioctl
and during this time the device is suspended, the complete for this
gets called from mdp_histogram_ctrl_all() in the panel_next_off()
sequence. This results in mgmt->hist not set to NULL. The subsequent
do_histogram ioctls after device resume fail due to multiple reader
failure condition since the histogram irq will be enabled now from
the same mdp_histogram_ctrl_all() during panel_next_on() sequence and
this by-passes mgmt->hist getting set to NULL that is present in
histogram_start() ioctl. Handle this scenario.

This reverts commit 2423ba8ae07458ec93efa07d777454f26d1d7c90.
commit 2423ba8... will be refered to as commit X
Commit X should have been listed as a parent of commit
56a123baaab84af584fbbf5cbb29955ec5c92f39 (i.e. video: msm: Always queue
histogram work & lock histogram calls).
commit 56a123b... will be refered to as commit Y
Commit Y is composed of 3 commits that were squashed together after they
caused errors when only one of them merged into mainline. Commit X was
created to revert the first of these 3 commits, and thus resolve the
errors.
However, when updating commit Y, commit X was omitted as the parent commit.
So when commit Y merged as a parent of commit X, commit X reverted part of
commit Y. By reverting commit X, this commit restores commit Y.

gpu: ion: several bugfixes and enhancements of ION
1. Verifying if the size of memory allocation in ion_alloc() is aligned
by PAGE_SIZE at least. If it is not, this change makes the size to be
aligned by PAGE_SIZE.
2. Unmaps all mappings to the kernel and DMA address spaces when
destroying ion_buffer in ion_buffer_destroy(). This prevents leaks in
those virtual address spaces.
3. Makes the return value of ion_alloc() to be explicit Linux error code
when it fails to allocate a buffer.
4. Makes ion_alloc() implementation simpler. Removes 'goto' statement and
relavant call to ion_buffer_put().
5. Checks if the task is valid before calling put_task_struct() due
to failure on creating a ion client in ion_client_create().
6. Returns error when buffer allocation requested by userspace is failed.
