[PATCH v2 31/33] tools lib bpf: Renaming pr_warning to pr_warn

From: Kefeng Wang
Date: Fri Oct 18 2019 - 01:06:39 EST

For kernel logging macro, pr_warning is completely removed and
replaced by pr_warn, using pr_warn in tools lib bpf for symmetry
to kernel logging macro, then we could drop pr_warning in the
whole linux code.
