scsi: mpi3mr: Clear reset history on ready and recheck state after timeout

The driver retains reset history even after the IOC has successfully
reached the READY state. That leaves stale reset information active during
normal operation and can mislead recovery and diagnostics. In addition, if
the IOC becomes READY just as the ready timeout loop exits, the driver
still follows the failure path and may retry or report failure incorrectly.

Clear reset history once READY is confirmed so driver state matches actual
IOC status. After the timeout loop, recheck the IOC state and treat READY
as success instead of failing.
