bpf, core: Fix kernel-doc notation 

Fix kernel-doc warnings in kernel/bpf/core.c (found by scripts/kernel-doc
and W=1 builds). That is, correct a function name in a comment and add
return descriptions for 2 functions.

Fixes these kernel-doc warnings:

  kernel/bpf/core.c:1372: warning: expecting prototype for __bpf_prog_run(). Prototype was for ___bpf_prog_run() instead
  kernel/bpf/core.c:1372: warning: No description found for return value of '___bpf_prog_run'
  kernel/bpf/core.c:1883: warning: No description found for return value of 'bpf_prog_select_runtime'
