[pve-devel] [PATCH qemu-server 1/3] restore vma: fix applying storage-specific bandwidth limit

[Fabian Ebner <f.ebner@proxmox.com>]

At this stage, there are no keys in %storage_limits to iterate over. The
refactoring in commit 9f3d73bc353c79f84498122b779764184f504005 broke the logic
by accident.

Also explicitly set zero if there is no limit to avoid repeating the
get_bandwith_limit call for the same storage. When accessing the value later,
zero is already correctly handled as 'no limit'.
