[pve-devel] [PATCH manager stable-7] pve7to8: content-dirs check: skip paths that cannot be resolved

[Friedrich Weber <f.weber@proxmox.com>]

The current inequality check for content-dirs does not correctly
handle the case in which `abs_path` returns undef. This can result in
confusing warnings:

  storage [...] uses directory  for multiple content types [...]

Fix this by skipping paths for which `abs_path` returns undef. This
matches the behavior of the actual content-dirs check in PVE 8 [0].
