Use pcie_capability_read_word() for reading LNKSTA and remove the
custom define that matches to PCI_EXP_LNKSTA.
As only single user for cap_offset remains, replace it with a call to
pci_pcie_cap(). Instead of e1000_adapter, make local variable out of
pci_dev because both users are interested in it.
