zram: reject zero-size dictionary
kernel_read_file_from_path() already rejects empty files (i_size <= 0) and
returns -EINVAL, but the current implementation only checks for sz < 0
without logging any information. Use sz == 0 to reject the zero-size case
and print distinct error messages for each failure type.
