bpf: flatten bpf_probe_register call chain 

bpf_probe_register() and __bpf_probe_register() have identical
signatures and bpf_probe_register() just redirect to
__bpf_probe_register(). So get rid of this extra function call step to
simplify following the source code.

It has no difference at runtime due to inlining, of course.
