If available, use the device's LOGICAL blocksize as reported by
the "READ_CAPACITY" command, rather than the physical blocksize
reported in the physical geometry code-page.

Also don't print out worrying bogus messages when probing a
device that has no media. There's no point in printing out
something that is unknowable. It just confuses things.

Move the check for valid blocksize out of 'open()' to the subroutine
that actually finds this out, thus probe/attach can also report and
act on the problem.
