scsi: mpt3sas: Prevent sending diag_reset when the controller is ready

If the driver detects that the controller is not ready before sending the
first IOC facts command, it will wait for a maximum of 10 seconds for it to
become ready. However, even if the controller becomes ready within 10
seconds, the driver will still issue a diagnostic reset.

Modify the driver to avoid sending a diag reset if the controller becomes
ready within the 10-second wait time.
