net: tipc: avoid possible garbage value

Clang static checker (scan-build) warning:
net/tipc/bcast.c:305:4:
The expression is an uninitialized value. The computed value will also
be garbage [core.uninitialized.Assign]
  305 |                         (*cong_link_cnt)++;
      |                         ^~~~~~~~~~~~~~~~~~

tipc_rcast_xmit() will increase cong_link_cnt's value, but cong_link_cnt
is uninitialized. Although it won't really cause a problem, it's better
to fix it.

Fixes: dca4a17d24ee ("tipc: fix potential hanging after b/rcast changing")
