selftest: net: fix socklen_t type mismatch in sctp_collision test

Socket APIs like recvfrom(), accept(), and getsockname() expect socklen_t*
arg, but tests were using int variables. This causes -Wpointer-sign
warnings on platforms where socklen_t is unsigned.

Change the variable type from int to socklen_t to resolve the warning and
ensure type safety across platforms.

warning fixed:

sctp_collision.c:62:70: warning: passing 'int *' to parameter of
type 'socklen_t *' (aka 'unsigned int *') converts between pointers to
integer types with different sign [-Wpointer-sign]
   62 |                 ret = recvfrom(sd, buf, sizeof(buf),
									0, (struct sockaddr *)&daddr, &len);
      |                                                           ^~~~
