patch 9.0.0373: Coverity warns for NULL check and unused return value
Problem: Coverity warns for NULL check and unused return value.
Solution: Remove the NULL check, it was already checked earlier. Add (void)
to ignore the return value.

| 7 | 1 :: Start Vim on a copy of the tutor file. |
| 2 @echo off | |
| 3 | |
| 4 :: Usage: vimtutor [-console] [xx] | |
| 5 :: | |
| 6 :: -console means gvim will not be used | |
| 7 :: xx is a language code like "es" or "nl". | |
| 8 :: When an xx argument is given, it tries loading that tutor. | |
| 9 :: When this fails or no xx argument was given, it tries using 'v:lang' | |
| 10 :: When that also fails, it uses the English version. | |
| 11 | |
| 12 :: Use Vim to copy the tutor, it knows the value of $VIMRUNTIME | |
