[PATCH] mke2fs: be explicit if external journal device is not found

[Eric Sandeen <sandeen@redhat.com>]

This for RH bug #572935 -
RFE: Misleading error message from mke2fs -J option

If the journal device UUID is typo'd or otherwise not found,
the error message looks like it's a usage() type of problem.

It'd be helpful to explicitly say that the device requested
could not be found.
