rtl818x: check for pci_map_single() success when initializing RX ring
During initialization a number of RX skbs are allocated and mapped
for DMA.
Currently if pci_map_single() fails, it will result in passing to the
HW a wrong DMA address (to write to!).
This patch adds check for this condition and eventually causes the
driver not to initialize, avoiding at least dangerous DMAs.
