Re: [PATCH 2/3] samples: bpf: cleanup pointer error check with libbpf

Libbpf has its own helper function to check for errors in the bpf
data structure (pointer). And Some codes do not use this libbbpf
helper function and check the pointer's error directly.

This commit clean up the existing pointer error check logic with
libbpf.

This entire patch is wrong. bpf_object__find_program_by_name() returns
NULL if the program is not found, not an error code.
