If there was a error during the process operation the output of zero bytes
was still being allocated. This causes a trace to occur in vmalloc.
Skip allocating and copying output on error.

The dce test code was broken when focus was placed on bman usage.
Fixed test code when using pre-built buffers.
Added verbosity level to test cases.
Change kernel help api name to explicitly name output buffer as this is
consistent with bman api.

Add modules to self test fsl DCE hardware accelerator.
1) dce_chunk_comp_def_cf_tester.ko
This module tests the chunk based (de)compression using deflate and compound frames.
2) dce_simple_perf_tester.ko
This module can be used to measure dce performance throughput.
The associated README file describes the usage.

The fsl_dce_stream object enables the user to do stream based (de)compression.
As opposed to chunk based compression where all the data in a single frame is
sent to the DCE device, stream based (de)compression permits the user to send
mulitple frames and receive the corresponding resuls in multiple frames.

The fsl_dce device does compression and decompression of
various formats (deflate, zlib, gzip).
The flib directory contains the base layer object required
to access the dce device. The fsl_dce_flow object contains the
minimum set of interfaces required to send and receive frames
to/from the dce via QMan.
The fsl_dce_chunk object is an extension of the fsl_dce_flow object.
This object is used to compress or decompress single frames (chunks)
at a time.
