Fix bug: return correctly from sub

[mikkoi]

I was getting errors like this in Git when I pushed to remote host:

remote: Exiting subroutine via next at [..]/local/lib/perl5/Git/Hooks/CheckWhitespace.pm line 30.

The command next should not be used to return from a sub.

[..]
next cannot return a value from a block that typically returns a value,
such as eval {}, sub {}, or do {}. It will perform its flow control
behavior, which precludes any return value. It should not be used
to exit a grep or map operation.
