x86/HVM/emul: address violations of MISRA C:2012 Rules 8.2 and 8.3

Give a name to unnamed parameters thus addressing violations of
MISRA C:2012 Rule 8.2 ("Function types shall be in prototype form with
named parameters").
Keep consistency between parameter names used in function declarations
and names used in the corresponding function definitions thus addressing
violations of MISRA C:2012 Rule 8.3 ("All declarations of an object or
function shall use the same names and type qualifiers").
