Fixes these errors:

net/ipv4/syncookies.c:216:19: error: 'struct tcp_request_sock' has no
member named 'drop_req'
  216 |   if (tcp_rsk(req)->drop_req) {
      |                   ^~
net/ipv4/syncookies.c: In function 'cookie_tcp_reqsk_alloc':
net/ipv4/syncookies.c:289:27: warning: unused variable 'treq'
[-Wunused-variable]
  289 |  struct tcp_request_sock *treq;
      |                           ^~~~
make[3]: *** [scripts/Makefile.build:280: net/ipv4/syncookies.o] Error 1
