MdeModulePkg/Variable: Make only EFI_VARIABLE_NON_VOLATILE invalid

MdeModulePkg/Variable: Make only EFI_VARIABLE_NON_VOLATILE invalid

Only EFI_VARIABLE_NON_VOLATILE attribute is an invalid combination
of attribute bits, so update the variable driver to return
EFI_INVALID_PARAMETER so that we can prevent the invalid variable
being created.

This change also fixes the SCT failure below:
 - RT.QueryVariableInfo - With being an invalid combination -- FAILURE
