This reverts commit 035db37394
Even though we only allow using RBD with raw volumes,
removing the options and the default format causes our
parser not to fill out the volume format and the backend code
rejects creating a non-raw volume.
Re-introduce the volume options to fix volume creation while
erroring out on requests to use non-raw formats.

Commit a7fb2258 added sanitization of storage pool target paths,
however source dir paths were left unsanitized.
A netfs pool with:
<source>
<host name='10.20.30.40'/>
<dir path='/nfs/'/>
</source>
will not be correctly detected as mounted by
virStorageBackendFileSystemIsMounted, because it shows up in the
mount list without the trailing slash.
Sanitize the source dir as well.
