[PATCH v2] Ifconfig : Fixed False information about Media State.

[Meenakshi Aggarwal <meenakshi.aggarwal@nxp.com>]

Issue : We were setting MediaPresent as TRUE (default), so
even if NetLibDetectMedia() did not set MediaPresent Flag as TRUE,
ifconfig always display Media State as 'Media Present'

Fix : Set MediaPresent as FALSE before calling NetLibDetectMedia()
