[zlib_bench] check deflate consumed all input

zlib_compress deflate() should consume all the input data. Add a check
and fail the deflation if there is unconsumed input data when the zlib deflate() call returns.

What about inflate()? zlib_bench knows the expected length of the data
(it is the original input length) and fails with a Z_DATA_ERROR if the zlib_uncompress inflate() output data length does not match.
