tcp: Remove unused but set variable

Remove the unused but set variable icsk in listening_get_next to fix the
following GCC warning when building with 'W=1':

  net/ipv4/tcp_ipv4.c: In function ‘listening_get_next’:
  net/ipv4/tcp_ipv4.c:1890:31: warning: variable ‘icsk’ set but not used [-Wunused-but-set-variable]
