Shung-Hsi Yu 44e9a741ca bpf: Determine buf_info inside check_buffer_access() 
Instead of determining buf_info string in the caller of check_buffer_access(),
we can determine whether the register type is read-only through
type_is_rdonly_mem() helper inside check_buffer_access() and construct
buf_info, making the code slightly cleaner.
