UPSTREAM: scsi: ufs: core: Rely on the block layer for setting RQF_PM

Browse Source 
Do not set RQF_PM explicitly since scsi_alloc_request() sets it indirectly
if BLK_MQ_REQ_PM is set. The call chain for the code that sets RQF_PM is as
follows:

    scsi_alloc_request()
      blk_mq_alloc_request()
        __blk_mq_alloc_requests()
          blk_mq_rq_ctx_init()
            if (data->flags & BLK_MQ_REQ_PM)
              data->rq_flags |= RQF_PM;
