e1000e: remove unnecessary internal msi state flag
Internal big flag E1000E_USE_MSI is unnecessary, also is the helper function: e1000e_init_msi(), e1000e_cleanup_msi(), so, remove them all. cc: Dmitry Fleytman <dmitry@daynix.com> cc: Jason Wang <jasowang@redhat.com> cc: Markus Armbruster <armbru@redhat.com> cc: Marcel Apfelbaum <marcel@redhat.com> cc: Michael S.
