crash_test: two fixes (#6200)

Browse Source 
Summary:
Fix two crash test issues:
1. sync mode should not run with disable_wal=true
2. disable "compaction_readahead_size" for now. With it on, some block checksum verification failure will happen in compaction paths. Not sure why, but disable it for now to keep the test clean.
Pull Request resolved: https://github.com/facebook/rocksdb/pull/6200

Test Plan: Run "make crash_test" and "make crash_test_with_atomic_flush" and see it runs way longer than before the fix without failing.
