description:
Make sure bp->b_proc is initialized.  Should fix a deref-garbage-pointer
problem reported by msaitoh%netbsd.org@localhost.  NOTE: These are marked XXXUBC
since the code that allocates the bufs is new with UBC, but it may be
the case that bp->b_proc needs to be intialized to curproc (it's used
in a call to nfs_sigintr()).
