commit 0b02c8c0d75a738c98c35f02efb36217c170d78c upsream.
Now that we only call xfs_update_prealloc_flags() from xfs_file_fallocate() in the case where we need to set the preallocation flag, do this in xfs_alloc_file_space() where we already have the inode joined into a transaction and get rid of the call to xfs_update_prealloc_flags() from the fallocate code.
This also means that we now correctly avoid setting the XFS_DIFLAG_PREALLOC flag when xfs_is_always_cow_inode() is true, as these inodes will never have preallocated extents.
