Recent changes to adbd have enabled nonblocking_ffs by default.
These have seeminly uncovered some bad memory corruption in the
kernel ffs gadget driver on every kernel I've tried so far.
Unfortunately I've not been able to diagnose what is going wrong,
so for now, lets disable the nonblocking_ffs.
We still need to root cause the issue as its a problem even with
the mainline kernel on HiKey, so its likely a generic kernel issue.

The kernel does not support aio with ffs.
Set the property so adb/mtp know to use the compatible
functions, and the same while in recovery.
Bug: 37916658
Test: Use adb / use adb in recovery
