[PATCH] system/vl: Free allocate memory for pid file name in case realpath() failed

From: Thomas Huth <[email protected]>

In case realpath() fails, the code returns early in the function
qemu_maybe_daemonize(), without freeing the allocated memory. Add
a g_free() here to fix it.

Fixes: dee2a4d4d2f ("vl: defuse PID file path resolve error")
