Fix leak in `purple_markup_find_tag` on error

The output is set to `NULL`, but the internal data list is not freed if it happened to get something put into it.

Fixes https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=35816

Testing Done:
Ran `pidgin_utils_fuzzer` on the test case in the bug report.

cat <<EOF
This program calls purple API functions using DBus. As opposed to purple-send,
it does not print the return value.
Usage:
$0 method-name type1:parameter1 type2:parameter2 ...
This shell script just invokes dbus-send, see man dbus-send for how
to specify the parameters.
Examples:
$0 PurpleCoreQuit
Use dbus-viewer to get the list of supported functions and their parameters.
