  Log:
  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.
