[dpdk-dev] [PATCH] compress/qat: fix status return on error building request

[Tomasz Jozwiak <tomaszx.jozwiak@intel.com>]

This patch fixes error status which should be set inside
qat_comp_build_request function in case any errors are detected.
In these cases op.status is set to
RTE_COMP_OP_STATUS_INVALID_ARGS to help application debug.

Fixes: 1947bd18580b ("compress/qat: support scatter-gather buffers")
