qapi: return a 'missing parameter' error 

The 'old' dispatch code returned a QERR_MISSING_PARAMETER for missing
parameters, but the qapi qmp_dispatch() code uses
QERR_INVALID_PARAMETER_TYPE.

Improve qapi code to return QERR_MISSING_PARAMETER where
appropriate.

Fix expected error message in iotests.
