tipc: fix dereference before check warning
This fixes the following Smatch warning:
net/tipc/link.c:2364 tipc_link_recv_fragment()
warn: variable dereferenced before check '*head' (see line 2361)
A null pointer might be passed to skb_try_coalesce if
a malicious sender injects orphan fragments on a link.
