Subject: [PATCH] lib/traceevent :  clean up clang build warning

The uniform structure filter_arg sets its union based
on the difference of enum filter_arg_type, However,
some functions use implicit type conversion obviously.

warning: implicit conversion from enumeration type 'enum filter_exp_type'
	 to different enumeration type 'enum filter_op_type'

warning: implicit conversion from enumeration type 'enum filter_cmp_type'
	 to different enumeration type 'enum filter_exp_type'
