staging: rtl8192e: Remove function ..dm_check_ac_dc_power calling a script

commit 20e622494179a1094b24bde458640eb0a8d8c4fe upstream.

Remove function _rtl92e_dm_check_ac_dc_power calling a script
/etc/acpi/wireless-rtl-ac-dc-power.sh that is not available. This script
is not part of the kernel and it is not available on the www. The result
is that this function is just dead code.
