If the file system has a non-zero s_first_data_block, as is the case
when the block size is 1kb, e2freefrag would incorrectly try to
reference invalid data blocks in the block allocation bitmap.

"Free chunks" is confusing since it has nothing to do with the
chunksize; use "free extents" instead.
Also add a missing newline in an error message.
