scsi: hisi_sas: Run I_T nexus resets in parallel for clear nexus reset
For a clear nexus reset operation, the I_T nexus resets are executed
serially for each device. For devices attached through an expander, this
may take 2s per device; so, in total, could take a long time.
Reduce the total time by running the I_T nexus resets in parallel through
async operations.
