[PULL for-6.1 4/6] qga-win: Free GMatchInfo properly

[Michael Roth <michael.roth@amd.com>]

From: Kostiantyn Kostiuk <konstantin@daynix.com>

The g_regex_match function creates match_info even if it
returns FALSE. So we should always call g_match_info_free.
A better solution is using g_autoptr for match_info variable.
