When building with --enable-sanitizers we get:
Direct leak of 32 byte(s) in 2 object(s) allocated from:
#0 0x5618479ec7cf in malloc (qemu-system-aarch64+0x233b7cf)
#1 0x7f675745f958 in g_malloc (/lib64/libglib-2.0.so.0+0x58958)

Similarly to commit d710e1e7bd3 ("usb: ehci: fix memory leak in
ehci"), fix by calling usb_ehci_finalize() to free the USBPacket.
