Fix warnings: regexp_nfa.c: nfa_regatom(): Dead assignment: HI.

Browse Source 
Problem    : Dead assignment @ 1554.
Diagnostic : Harmless issue.
Rationale  : `result` is used when analyzing if a bracketed expresion
             `[<whatever>]` can be condensed into a character class. Not
             used for anything else anywhere. So, it's safe to remove.
Resolution : Remove dead assingment and move declaration of `result` to
             the scope where it's used.
