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
