[PATCH] scsi - gvp11.c: fix DMA mask calculation error

[Michael Schmitz <schmitzmic@gmail.com>]

DMA masks given in the Zorro ID table don't contain the 2 byte
alignment quirk seen in the GVP11_XFER_MASK macro from gvp11.h
so no need to account for that.

DMA masks passed to dma_set_mask_and_coherent() must be 64 bit,
add the missing cast in the TO_DMA_MASK macro used to convert
driver DMA masks to DMA API masks.
