db_bench segfaults on malformed URI string

./db_bench --benchmarks=fillseq --num=1000000 --value_size=800 --histogram --fs_uri=zenfs://nvme1n1 Received signal 11 (Segmentation fault)

--fs_uri=zenfs://nvme1n1 is not correct, it needs a dev: prefix, but the error should not result in a segfault.

This issue is not seen with latest rocksdb master, after PR https://github.com/facebook/rocksdb/pull/9333

db_bench fails, instead of segmentation fault. Rocksdb is now propagating the error code from underlying plugin to the application.

sudo ./db_bench --benchmarks=fillseq --num=1000000 --value_size=800 --histogram --fs_uri=zenfs://nvme0n1 Failed creating env: Invalid argument: Malformed URI: zenfs://nvme0n1
