fuse: lock inode unconditionally in fuse_fallocate()
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.
