History
Konstantin Belousov f2e6bf5c05 Account for lock recursion when transfering snaplock to the vnode lock 
in ffs_snapremove().

Apparently ffs_snapremove() may be called with the snap lock recursed,
at least one trace demonstrated this when snapshot vnode was unlinked
while synced.  It was inactivated from the syncer thread.
