e1000e: Use pcie_capability_read_word() for reading LNKSTA
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.
