scsi: gvp11.c: Fix DMA mask calculation error
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.
