scsi: wd719x: Return proper error code when dma_set_mask() fails

Browse source 
During the process of driver probing, the probe function should return < 0
for failure, otherwise the kernel will treat value >= 0 as success.

Set 'err' to the error value returned by dma_set_mask() in case of failure.
