[PATCH] mailmap: remove redundant check for freeing memory

[Stefan Beller <stefanbeller@googlemail.com>]

The condition as it is written in that line has already been checked
in the beginning of the function, which was introduced in
8503ee4 (2007-05-01, Fix read_mailmap to handle a caller uninterested
in repo abbreviation)
