  pf: Rename pfsync bucket lock
  
  Previously the main pfsync lock and the bucket locks shared the same name.
  This lead to spurious warnings from WITNESS like this:
  
      acquiring duplicate lock of same type: "pfsync"
       1st pfsync @ /usr/src/sys/netpfil/pf/if_pfsync.c:1402
       2nd pfsync @ /usr/src/sys/netpfil/pf/if_pfsync.c:1429
  
  It's perfectly okay to grab both the main pfsync lock and a bucket lock at the
  same time.
  
  We don't need different names for each bucket lock, because we should always
  only acquire a single one of those at a time.
