r1.118 starting using LINK_STATE_IS_UP() to check the link status

info provided in RTM_IFINFO messages. But it didn't replicate the
checks for IFI_NOMEDIA and (IFF_UP | IFF_RUNNING) used in
interface_status() to set ifi->linkstat. So the test (LINK_STATE_IS_UP()
!= ifi->linkstat) was comparing kiwi fruit and hairballs.

Do the additional checks using info present in the RTM_IFINFO
message.  As a result interface_status() need not be called to
update ifi->linkstat. Thus avoiding opening/closing a socket and
some ioctls to re-obtain the info already provided in the RTM_IFINFO
message.
