UBIFS: fix no_chk_data_crc
When data CRC checking is disabled, UBIFS returns incorrect return code from the 'try_read_node()' function (0 instead of 1, which means CRC error), which make the caller re-read the data node again, but using a different code patch, so the second read is fine. Thus, we read the same node twice. And the result of this is that UBIFS is slower with no_chk_data_crc option than it is with chk_data_crc option. This patches fixes the problem.
