[pve-devel] [PATCH storage] fix prune-backups validation (again)

Commit a000e26ce7d30ba2b938402164a9a15e66dd123e caused a test failure
in pve-manager, because now 'keep-all=0' is not thrown out upon
validation anymore. Fix the issue the commit addressed differently,
by simply creating a copy of the (shallow) hash first, and using
the logic from before the commit.
