Miklos Szeredi f2fb18d429 fuse: lock inode unconditionally in fuse_fallocate() ...

commit 44361e8cf9 upstream.

file_modified() must be called with inode lock held.  fuse_fallocate()
didn't lock the inode in case of just FALLOC_KEEP_SIZE flags value, which
resulted in a kernel Warning in notify_change().

Lock the inode unconditionally, like all other fallocate implementations
do.
