Fix potential leak in macspellimp.mm

+ avoid macSpell var
I'm not sure to retrieve [NSSpellChecker sharedSpellChecker] in a pointer
is a good idea.
Most of the examples using sharedSpellChecker just call [NSSpellChecker sharedSpellChecker]
each time. If there's a bit more code, at least we're sure we won't leak because of this.
