compress/isal: fix offset check
compress/isal: fix offset check

This commit fixes an offset check in decompression which was checking
destination offset size against dst data_len rather than checking
against dst pkt_len as required, to support single and multi-segment
buffers.

Fixes: 788e748d3845 ("compress/isal: support chained mbufs")
