From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
Currently the exit return path when sme->key_idx >= NUM_WEPKEYS is via
label 'exit' and this checks if result is non-zero, however result has
not been initialized and contains garbage. Fix this by replacing the
goto with a return with the error code.
Addresses-Coverity: ("Uninitialized scalar variable")
Fixes: 0ca6d8e74489 ("Staging: wlan-ng: replace switch-case statements with macro")
