patch 9.1.0633: Compilation warnings with `-Wunused-parameter`
Problem: Compilation warnings with `-Wunused-parameter`
Solution: Add the `UNUSED` macro where needed, and remove some
superfluous ones (Dominique Pellé)
Change fixes these kind of warnings when building without the channel
feature:
```
eval.c:6122:15: warning: unused parameter ‘tv’ [-Wunused-parameter]
typval_T *tv,
^
eval.c:6123:14: warning: unused parameter ‘tofree’ [-Wunused-parameter]
char_u **tofree,
^
eval.c:6124:13: warning: unused parameter ‘numbuf’ [-Wunused-parameter]
char_u *numbuf,
^
eval.c:6125:10: warning: unused parameter ‘composite_val’ [-Wunused-parameter]
int composite_val)
```
