Shrink ashmem directly through shmem_fallocate
When ashmem_shrink is called from direct reclaim on a user thread, a
call to do_fallocate will check for permissions against the security
policy of that user thread. It can thus fail by chance if called on a
thread that isn't permitted to modify the relevant ashmem areas.
Because we know that we have a shmem file underneath, call the shmem
implementation of fallocate directly instead of going through the
user-space interface for fallocate.
