[pve-devel] [PATCH qemu-server] Create linked clone failed, uninitialized storage

[Alwin Antreich]

When creating a linked clone the storage parameter is not defined. The
get_bandwidth_limit method got a undef element for its storage_list and
therefore failed on trying to set the bandwidth limit.

This patch only pushes the storage parameter into the storage_list array
if it is defined.
