lorneli e3c26a054b bdev: reduce critical area in spdk_bdev_open
Since bdev->internal.mutex protects variables in bdev->internal,
there's no need to init the fields of spdk_bdev_desc struct and
free the struct when claim_module exists within the mutex lock.

Reducing critical area could help to reduce lock competition
caused by opening bdev concurrently.
