[SCSI] 3w-xxxx: remove unnecessary local_irq_save/restore for scsi sg copy API 

Since the commit 50bed2e286 (sg: disable
interrupts inside sg_copy_buffer), no need to disable interrupts
before calling scsi_sg_copy_from_buffer. So we can simplify
tw_transfer_internal, which disables interrupts just for
scsi_sg_copy_from_buffer.
