Peter Wemm 9733f8ee44 Hold a reference to the vnode during the sillyrename cleanup. If we block ...

in nfs_vinvalbuf() or the nfs_removeit(), we can have the nfsnode reallocated
from underneath us (eg: replaced by a ufs 'struct inode') which can cause
disk corruption ('freeing free block' when di_db[5] gets trashed).
This is not a cheap fix, but it'll do until the nfsnodes get reference
counting and/or locking.

Apparently NetBSD have a similar fix (apparently from BSDI).

I wish all PR's had this much useful detail. :-)
