Yang Ruibin ce66d7c703 perf bpf: Remove redundant check that map is NULL ...

The check that map is NULL is already done in the bpf_map__fd(map) and
returns an errno, which does not run further checks.

In addition, even if the check for map is run, the return is a pointer,
which is not consistent with the err_number returned by bpf_map__fd(map).
