scsi: advansys: Don't call asc_prt_scsi_host() -> scsi_host_busy()

The driver calls asc_prt_scsi_host() -> scsi_host_busy() prior to
calling scsi_add_host(). This should not be done, and has raised issues
for other drivers, like [0].

Function asc_prt_scsi_host() only has a single callsite, as above, where
the shost busy count would always be 0.

Avoid printing the shost busy count to avoid this problem.
