Viktor Slavkovic b4106c55b5 staging: android: ashmem: fix a race condition in ASHMEM_SET_SIZE ioctl 
commit 443064cb0b upstream.

A lock-unlock is missing in ASHMEM_SET_SIZE ioctl which can result in a
race condition when mmap is called. After the !asma->file check, before
setting asma->size, asma->file can be set in mmap. That would result in
having different asma->size than the mapped memory size. Combined with
ASHMEM_UNPIN ioctl and shrinker invocation, this can result in memory
corruption.
