Revert "ANDROID: vendor_hooks: Add hook for binder_detect_low_async_space_locked"

Browse Source 
This reverts commit 7ce117301e.

The alloc->mutex to spinlock_t patches from [1] are being backported
into this branch. The vendor hooks will be reapplied on top of these
backports in a way that matches the new structure of the code.
