platform/x86: wmi: Avoid returning AE_OK upon unknown error
If an error code other than EINVAL, ENODEV or ETIME is returned
by ec_read()/ec_write(), then AE_OK is wrongly returned.
Fix this by only returning AE_OK if the return code is 0, and
return AE_ERROR otherwise.
Tested on a Dell Inspiron 3505 and a Asus Prime B650-Plus.
