        src/sys/kern [netbsd-9]: subr_pool.c

Log Message:
Pull up following revision(s) (requested by bouyer in ticket #1956):

        sys/kern/subr_pool.c: revision 1.295

Never call pr_drain_hook from pool_allocator_alloc().

In the PR_WAITOK case it's called from pool_reclaim

In the !PR_WAITOK case we're holding the pool lock and if the drain hook
  wants kernel_lock we may deadlock with another thread holding
  kernel_lock and calling pool_get().

Fixes PR kern/59411
