3c59x: fix missing dma_mapping_error check and bad ring refill logic
A few spots in 3c59x missed calls to dma_mapping_error checks, casuing
WARN_ONS to trigger. Clean those up. While we're at it, refactor the
refill code a bit so that if skb allocation or dma mapping fails, we
recycle the existing buffer. This prevents holes in the rx ring, and
makes for much simpler logic
Note: This is compile only tested. Ted, if you could run this and
confirm that it continues to work properly, I would appreciate it, as I
currently don't have access to this hardware
