Subject: [PATCH 1/3] Staging: rtl8192e: Do not mess with carrier settings while scanning

Toggling the link carrier is a non sense and is the grossest locking I can
think of. Moreover, it's giving a completely inaccurate status to userspace
who could for example decide to turn the interface down on carrier off
detection.
