scsi: mpt3sas: Fix loop logic

Browse source

commit 3c978492c3 upstream.

The retry loop continues to iterate until the count reaches 30, even after
receiving the correct value. Exit loop when a non-zero value is read.

Fixes: 4ca10f3e31 ("scsi: mpt3sas: Perform additional retries if doorbell read returns 0")
