bpf: Remove blank line in bpf helper description comment

Browse Source 
Commit 34b2021cc6 ("bpf: Add BPF-helper for MTU checking") added an extra
blank line in bpf helper description. This will make bpf_helpers_doc.py stop
building bpf_helper_defs.h immediately after bpf_check_mtu(), which will
affect future added functions.
