[SCSI] mpt2sas: setting SDEV into RUNNING state from Interrupt context

Browse source

Changing SDEV Running state from interrupt context. Previously It was
handle in work queue thread. With this change It will not wait for work
queue thread to execute scsih_ublock_io_device to put SDEV into Running
state. This will reduce delay for Device becoming RUNNING.

Modified this patch considering James comment "Not to change SDEV state
using  scsi_device_set_state API, instead use scsi_internal_device_unblock
scsi_internal_device_block API"
