scsi: mpt3sas: Fix secure erase premature termination
This is a work around for a bug with LSI Fusion MPT SAS2 when perfoming secure erase. Due to the very long time the operation takes, commands issued during the erase will time out and will trigger execution of the abort hook. Even though the abort hook is called for the specific command which timed out, this leads to entire device halt (scsi_state terminated) and premature termination of the secure erase. Set device state to busy while ATA passthrough commands are in progress.
