bcachefs: mark bch_inode_info and bkey_cached as reclaimable

Browse Source 
Mark these caches as reclaimable, so that available memory is correctly
reported when there is a lot of cached inodes.

Note that more work is needed - you should add __GFP_RECLAIMABLE to some
of the kmalloc calls, so that they are allocated from the "kmalloc-rcl-*"
caches.
