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:
