numa: mempolicy: trivial debug fixes.
Enabling debugging fails to build due to the nodemask variable in
do_mbind() having changed names, and then oopses on boot due to the
assumption that the nodemask can be dereferenced -- which doesn't work out
so well when the policy is changed to MPOL_DEFAULT with a NULL nodemask by
numa_default_policy().
This fixes it up, and switches from PDprintk() to pr_debug() while
we're at it.
