userland mount helper mount.cifs.

Also uppercase the now used (kernel) "orig_dev" parameter, to get the
mount retry working again.

Cheers, Günter

Subject: [PATCH] on 2nd try mount.cifs must also uppercase "orig_dev" - recent
 kernels now ignore "unc=..." mount option

mount.cifs.c, when getting errno=ENXIO, retries the mount with uppercased
hostname, sharename and prefixpath in the "unc=..." mount option, which
is ignored now in the kernel. Used e.g. during OS/2 mounts, which fail now.

Also uppercase the now used "orig_dev" parameter.
