Ifconfig : Fixed False information about Media State. 

Issue : We were setting MediaPresent as TRUE (default) and
not checking return status of NetLibDetectMedia().
NetLibDetectMedia() sets MediaPresent FLAG in case of success
only and dont change flag on error.
So, Media State will display as 'Media Present', in case of
error also.

Fix : Check return value of NetLibDetectMedia(), if error then
print "Media State Unknown"
