fix: cmd_object_put check not exists bucket

In the cmd_object_put function, after checking the type of the URL,
verify whether the passed bucket exists.

The reason for doing this is that in a self-built S3 Server, I attempted
to upload to a non-existent bucket using s3cmd, similar to
's3cmd put hello s3://b02', where b02does not exist, but the operation
still succeeded(and the file could even be downloaded). This issue arises
due to a design flaw in our S3 Server.

$ ./s3cmd put setup.cfg s3://b02
upload: 'setup.cfg' -> 's3://b02/setup.cfg'  [1 of 1]
56 of 56   100% in    0s    11.63 KB/s  done

$ mc put setup.cfg myio/b02
mc: <ERROR> unable to upload. Bucket `b02` does not exist.

However, similar clients like the MinIO client would directly return an
error stating that the bucket b02 does not exist.Therefore, I believe it
is necessary for s3cmd to include this check.

$ ./s3cmd put setup.cfg s3://b02
ERROR: Bucket 'b02' does not exist
