Branch: MAIN
CVS Tags: OPENBSD_7_5_BASE, OPENBSD_7_5, OPENBSD_7_4_BASE, OPENBSD_7_4, OPENBSD_7_3_BASE, OPENBSD_7_3, OPENBSD_7_2_BASE, OPENBSD_7_2, OPENBSD_7_1_BASE, OPENBSD_7_1, HEAD
Changes since 1.22: +3 -1 lines 

Shuffle some SCSIDEBUG code to simplify code, tersify the
emitted verbiage, and show INQUIRY header & vendor info early so
humans can more easily determine what scsi_probe_link() will
do.

No functional change outside SCSIDEBUG.
