mount: don't treat temporary name resolution failure as permanent

If getaddrinfo() returns EAI_AGAIN, we shouldn't just give up, but
should continue normal retries as the nameserver may be unavailable
for the same reason as the NFS server.

So move the getaddrinfo() call from nfs_validate_options() into
nfs_try_mount() which is always called soon after, except in the
'remount' case when we don't want it anyway.

If EAI_AGAIN is returned, set errno to EAGAIN and allow this to be a
temporary failure.  Otherwise report error and set errno to EALREADY
so no further message is given.
