Modified Files:
        src/sys/fs/union: union_subr.c

Log Message:
When union_allocvp() finds a node being cleaned out and the caller holds
a lock, ignore the node and continue.  To allow the cleaning to succeed
the current threadmust make progress.
For a brief time the cache may contain more than one vnode referring to
a lower node.

Don't unlock the hash mutex if getnewvnode fails -- we don't hold it.
