platform/x86: hp-bioscfg: fix a signedness bug in hp_wmi_perform_query()

Browse source

The error handling won't work if "mid" is unsigned.  "ret" is used to
store negative error codes and declaring it as a u32 won't cause a bug
but it's ugly.  The "actual_outsize" variable is a number between 0-4096
so it can be declared as int as well.
