[SCSI] mpt2sas: Call init_completion on a per request basis.
Now driver call init_completion on a per request basis. At some point the wait_for_completion_timeout is not waiting for the timeout, instead returning immediately, thus going into diag reset. This fix will address all request using the wait_for_completion_timeout API. The previous implimentation was only calling init_completion at driver load time.
