netfilter: core: remove erroneous warn_on
kernel test robot reported:
WARNING: CPU: 0 PID: 1244 at net/netfilter/core.c:218 __nf_hook_entries_try_shrink+0x49/0xcd
[..]
After allowing batching in nf_unregister_net_hooks its possible that an earlier
call to __nf_hook_entries_try_shrink already compacted the list.
If this happens we don't need to do anything.
Fixes: d3ad2c17b4047 ("netfilter: core: batch nf_unregister_net_hooks synchronize_net calls")
