Modified Files:
	src/sys/ufs/ffs: ffs_softdep.c

Log Message:
softdep_sync_metadata: If vp is a block device it may have new I/O requests
posted for it even if the vnode is locked. This will deadlock with wmesg
"softgetdbuf" if it gets a BMSAFEMAP dependency as here we have "bp == nbp"
and try to get a buffer we already own.
