tools: ynl: don't leak mcast_groups on init error
[ Upstream commit 5d78b73e851455d525a064f3b042b29fdc0c1a4a ]
Make sure to free the already-parsed mcast_groups if
we don't get an ack from the kernel when reading family info.
This is part of the ynl_sock_create() error path, so we won't
get a call to ynl_sock_destroy() to free them later.
