Turn the compression_type check in BlobDBImpl::DecompressSlice into an assertion (#7127)

Browse Source 
Summary:
In both cases where `BlobDBImpl::DecompressSlice` is called,
`compression_type` is already checked at the call site; thus, the check
inside the method is redundant and can be turned into an assertion.

Pull Request resolved: https://github.com/facebook/rocksdb/pull/7127

Test Plan: `make check`
