ixgbe: use ixgbe_read_pci_cfg_word 

This patch replaces some direct uses of pci_read_config_word with the
protected ixgbe_read_pci_cfg_word function, which checks for whether the
adapter is removed when LER is enabled. We shouldn't use the
pci_read_config_word calls directly because of these checks.

This patch also cleans up an unnecessary save of a pointer to the mac
object, as our standard style is to just use the hw pointer.
