staging: rtl8192e: Remove call_usermodehelper starting RadioPower.sh

commit fc9c516335f808ca4f139d7d2704d43a922e38e5 upstream.

Remove call_usermodehelper starting /etc/acpi/events/RadioPower.sh that
is not available. This script is not part of the kernel and it is not
officially available on the www. The result is that this lines are just
dead code.
