There are a couple of arguments of the boolean flag zero_size_allowed
and the char pointer buf_info when calling to function check_buffer_access
that are swapped by mistake. Fix these by swapping them to correct
the argument ordering.

Thanks for the fix!

Sigh, thanks for the fix Colin, applied! Yonghong, could you follow-up with
BPF selftest test cases that exercise these paths? Thx
