[PATCH 1/3] mount.nfs: Continue to trying address when the server return ENOENT

[Steve Dickson <steved@redhat.com>]

With recent changes to the /etc/hosts file, the 'localhost'
is now multiply defined as both an IPv4 address (127.0.01)
and an IPv6 address (::1). This change causes first address
returned by getaddrinfo('localhost') to be the IPv6 address
instead of the IPv4 address.

The change in the default 'localhost' address type causes
existing exports using '127.0.0.1' to fail, because the
'::1' address is tried first and fails. The problem
being not all the addresses that are returned by
getaddrinfo('localhost') are tried.

So this patch allows that address list to continue to be
process when the 'ENOENT' error is returned by the server.
