p54pci: don't return zero on failure paths in p54p_probe()

If pci_set_dma_mask() or pci_set_consistent_dma_mask() fails in p54p_probe(),
it breaks off initialization, deallocates all resources, but returns zero.
Similar issue is if check for returned value of pci_resource_len() fails.

The patch implements proper error code propagation.
