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. Signed-off-by:
