net/core/filter: fix unused-variable warning
Building with CONFIG_INET=n will show the warning below:
net/core/filter.c: In function ‘____bpf_getsockopt’:
net/core/filter.c:4048:19: warning: unused variable ‘tp’ [-Wunused-variable]
struct tcp_sock *tp;
^~
net/core/filter.c:4046:31: warning: unused variable ‘icsk’ [-Wunused-variable]
struct inet_connection_sock *icsk;
^~~~
Move the variable declarations inside the {} block where they are used.
Fixes: 1e215300f138 ("bpf: add TCP_SAVE_SYN/TCP_SAVED_SYN options for bpf_(set|get)sockopt")
