Matthew Dillon bcc740c453 Do not cluster with B_LOCKED buffers. 
This is an odd one.  This patch appears to fix a panic related to background
bitmap writes (for FFS), though neither Kirk, Ian, or I can figure out how
B_CLUSTEROK could possibly be set on a bitmap block to cause the clustering
code to improperly cluster with a buffer undergoing a background write.

In anycase, the clustering code is very fragile and this patch helps with
that, as well as possibly fixing a bug Andre was having.
