Avoid memory leaks upon (de)compression failure
This e.g. reduces the LSan-reported leakage during CppunitTest_sd_filters_test from SUMMARY: AddressSanitizer: 504104 byte(s) leaked in 4654 allocation(s). to SUMMARY: AddressSanitizer: 115048 byte(s) leaked in 4639 allocation(s). Change-Id: If922e872d9f696847face198e082144ccd5f12de
