[rpcli] DoScsiInquiry(): Fix an inverted condition that broke SCSI inquiry.

It was showing an error if the file specified was in fact a device file,
which prevents it from working.

This fixes a regression from commit 837315505e.
([rpcli] rpcli.cpp: Un-indent a few functions.)

Affects: v2.3 - v2.5
