[PATCH pve-storage 1/2] rbd plugin: do not use cache in list_images()

[Dmitry Petrov]

A static cache key 'rbd' was used to cache pool/storeid-specific
information. This was causing issues in case of multiple RBD pools.

Drop $cache usage instead of fixing the issue as there is no caller
using it and the same pool/storeid multiple times.

Remove $pool from rbd_ls() and get_rbd_path($scfg) from list_images().
