[PATCH 234/577] Staging: rtl8187se: Do not mess with carrier settings while scanning

From: Samuel Ortiz <sameo at linux.intel.com>

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.
