Add option to run inquiry only with scsidump

[akuker]

There have been several times while developing where it would be useful to just send an Inquiry command to a device to make sure its responding. I'd like to add a feature to scsidump to only run the inquiry command, report the results, then exit.

It would be worth exploring if the PiSCSI hardware will allow us to loop through and TestUnitReady / Inquiry each SCSI device to see what else is on the bus. This should be a separate "Mode" though.
