A mpath object can hold reference on a list of skb that are waiting for
mpath resolution to be sent. When destroying a mpath this skb list
should be cleaned up in order to not leak memory.
Fixing that kind of leak:
unreferenced object 0xffff0000181c9300 (size 1088):
comm "openvpn", pid 1782, jiffies 4295071698 (age 80.416s)
hex dump (first 32 bytes):
