[PATCH] mount.nfs: submarvellous messages from mount.nfs

[Steve Dickson <steved@redhat.com>]

From: Max Matveev <makc@redhat.com>

Consider a setup where mountd on the server is controlled via
tcp_wrappers (usual RHEL setup) and will not process calls from a
particular client because of something in /etc/hosts.deny.

When such client attempts to do v3 mount, the error message printed
by mount.nfs is misleading.

This patch changes that error message from:
    mount.nfs: Argument list too long
to
    mount.nfs: access denied by server while mounting server:/export
