[PATCH] Two small fixes for sym53c8xx_2

Both of these patches are originally by Grant Grundler.  They've been
tested in the PA-RISC tree for a few months, and I'm forwarding them along.

First patch:

pci_set_dma_mask returns 0 if the card can perform DMA as specified,
so the sense of the test is wrong.
