compress/zlib: fix error handling

[ upstream commit ff53baa9cc676249d1c5c514755d77e453a99b51 ]

Add missing return after setting the error status in case of
invalid flush_flag in the operation.
The issue was found by the coverity scan as the fin_flush variable,
not initialized in such case, was used later in the flow.

Coverity issue: 340859
Fixes: c7b436e ("compress/zlib: support burst enqueue/dequeue")
