When cleaning up from failed adv locking and checking for write, do

When cleaning up from failed adv locking and checking for write, do
not call VOP_CLOSE() manually.  Instead, delegate the close to
fo_close() performed as part of the fdrop() on the file failed to
open.  For this, finish constructing file on error, in particular, set
f_vnode and f_ops.

Forcibly resetting f_ops to badfileops disabled additional cleanups
performed by fo_close() for some file types, in this case it was noted
that cdevpriv data was corrupted.  Since fo_close() call must be
enabled for some file types, it makes more sense to enable it for all
files opened through vn_open_cred().
