[SCSI] arcmsr: simplify assumptions in dma_alloc_coherent()

The code currently computes an offset into a dma_alloc_coherent() area
on the assumption that the alignment is imprecise.  In fact, the API
guarantees PAGE_SIZE alignment, so the offset calculation is always
zero: remove it.

[jejb: make description actually descriptive]
