scsi: smartpqi: Add timeout value to RAID path requests to physical devices

Add a timeout value to requests sent to physical devices via the RAID
path.

A timeout value of zero means wait indefinitely, which may cause the OS
to issue Target Management Function (TMF) commands if the device does
not respond.

For input timeouts of 8 seconds or greater, the value sent to firmware
is reduced by 3 seconds to provide an earlier firmware timeout and allow
the OS additional time before timing out.

This change improves timeout handling between the driver, firmware, and
OS, helping to better manage device responsiveness and avoid indefinite
waits.
