[PATCH 1/1] mounts.nfs: v2 and v3 background mounts should retry when server is down.

[Steve Dickson <steved@xxxxxxxxxx>]

The point of background mounts is to have the mount
retried if the mount fails. This patch allows the v2/v3
background mount to proceed in the case when the server
is down by not making EOPNOTSUPP a permanent error.
