selftests/bpf: Close fd in error path in drop_on_reuseport

Browse Source 
[ Upstream commit adae187ebedcd95d02f045bc37dfecfd5b29434b ]

In the error path when update_lookup_map() fails in drop_on_reuseport in
prog_tests/sk_lookup.c, "server1", the fd of server 1, should be closed.
This patch fixes this by using "goto close_srv1" lable instead of "detach"
to close "server1" in this case.

Fixes: 0ab5539f85 ("selftests/bpf: Tests for BPF_SK_LOOKUP attach point")
