ACPI-EC: Drop unnecessary check made before calling acpi_ec_delete_query() 

Author: Markus Elfring <elfring@users.sourceforge.net>

The acpi_ec_delete_query() function tests whether its argument is NULL
and then returns immediately. Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.
