[PATCH V2] scripts/get_maintainer.pl: Fix possible infinite loop

[Joe Perches <joe@perches.com>]

This is simpler.

If MAINTAINERS section entries are misformatted,
it was possible to have an infinite loop.

Correct the defect by always moving the index
to the end of section + 1

Also, exit check for exclude as soon as possible.
