Suppress large kmem_alloc() warning.

Observed during failure mode testing, dsl_scan_setup_sync() allocates
73920 bytes.  This is way over the limit of what is wise to do with a
kmem_alloc() and it should probably be moved to a slab.  For now I'm
just flagging it with KM_NODEBUG to quiet the error until this can be
revisited.
