Don't run shrinkers without GFP_KERNEL

This would correspond to GFP_RECLAIM in the kernel - but we don't
distinguish between different types of reclaim here.

This solves a deadlock in the btree node memory allocation path - we
allocate with the btree node cache lock held but without GFP_KERNEL set.
