[PATCH] Revert "mountd: handle allocation failures in auth_unix_ip upcall"

["J. Bruce Fields" <bfields@fieldses.org>]

From: "J. Bruce Fields" <bfields@redhat.com>

This reverts commit 485f7a21e1649797f29317b865cbb094c1f6a71d.  The
failures handled there could be any sort of name resolution failure, not
just an allocation, and failing to downcall (hence leaving the client
hanging) is not the correct thing to do in those cases.
