tests/net/conn_mgr_nsos: Initialize address to 0 to avoid valgrind warning

aescolar · nashif · commit b6cd38149daa · 2026-05-20T20:08:45.000-04:00
Initialize the whole address to 0, to avoid a valgrind warning when
a copy of the address is passed to the Linux kernel:
```
Syscall param socketcall.sendto(to.sin_addr) points to uninitialised bytes
at _dl_sysinfo_int80 (in /usr/lib/i386-linux-gnu/ld-linux.so.2)
by sendto (sendto.c:30)
by nsos_adapt_sendto (nsos_adapt.c:544)
```
