[PATCH net-next] bpf: Remove unused but set variable in __bpf_lru_list_shrink_inactive()

[Tobias Klauser]

Remove the unused but set variable 'first_node' in
__bpf_lru_list_shrink_inactive() to fix the following GCC warning when
building with 'W=1':

  kernel/bpf/bpf_lru_list.c:216:41: warning: variable ‘first_node’ set but not 
used [-Wunused-but-set-variable]
