QAT: Fix uninitialized seed in QAT compression
CpaDcRqResults have to be initialized with checksum=1 for adler32. Otherwise when error CPA_DC_OVERFLOW occurred, the next compress operation will continue on previously part-compressed data, and write invalid checksum data. When zfs decompress the compressed data, a invalid checksum will occurred and lead to #14463 Reviewed-by: Tino Reichardt <milky-zfs@mcmilk.de> Reviewed-by: Weigang Li <weigang.li@intel.com> Reviewed-by: Chengfei Zhu <chengfeix.zhu@intel.com> Signed-off-by: naivekun <naivekun0817@gmail.com> Closes #14632 Closes #14463
