Added a check for non-zero virtual address.
Without this change, when ion_map_iommu returns a
zero virtual address, video core continuous ahead
without error check and later target reset happens
when trying to do a ion_unmap_iommu on the above fd,
which was never mapped.

In slice delivery mode, sometimes video hardware is giving
zero frame tag on output slices instead of input frame tag
value. This commit will fix the issue by copying the input
frame tag value to the output slice frame tag when video
hardware gives zero frame tag values.
