[PATCH 1/1] crypt32: Fix domain component length check.

[Erich E. Hoover]

Real Name:
    Erich Hoover

Description:
    This patch fixes an issue where the domain component in
match_domain_component will not match when the allowed_component is
NULL terminated.  This currently affects the Battle.net System Checker
(Bug #28162), which passes a server_component of "net" and an
allowed_component of "net\000".

Changelog:
    crypt32: Fix domain component length check.
