ACPI: APEI: remove redundant assignment to variable rc

Colin Ian King · rafaeljw · commit eb27e5a314d1 · 2020-07-27T15:22:58.000+02:00
The variable rc is being initialized with a value that is
never read and it is being updated later with a new value. The
initialization is redundant and can be removed.
