btrfs: fix slab cache flags for free space tree bitmap
commit 34e49994d0dcdb2d31d4d2908d04f4e9ce57e4d7 upstream.
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.
