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

[Cheng Jian]

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'
