Use thread-safe function pointer in libbpf_print
This patch fixes a thread safety bug where libbpf_print uses the
global variable storing the print function pointer rather than the local
variable that had the print function set via __atomic_load_n.
Fixes: f1cb927cdb62 ("libbpf: Ensure print callback usage is thread-safe")
