[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.
