[PATCH 02/16] xfs: remove debug assert for per-ag reference counting

From: Dave Chinner <dchinner at redhat.com>

When we start taking references per cached buffer to the the perag
it is cached on, it will blow the current debug maximum reference
count assert out of the water. The assert has never caught a bug,
and we have tracing to track changes if there ever is a problem,
so just remove it.
