btrfs: fix slab cache flags for free space tree bitmap
The free space tree bitmap slab cache is created with SLAB_RED_ZONE but that's a debugging flag and not always enabled. Also the other slabs are created with at least SLAB_MEM_SPREAD that we want as well to average the memory placement cost. Reported-by: Vlastimil Babka <vbabka@suse.cz> Fixes: 3acd48507dc4 ("btrfs: fix allocation of free space cache v1 bitmap pages") CC: stable@vger.kernel.org # 5.4+ Signed-off-by: David Sterba <dsterba@suse.com>
