[PATCH qemu-server v5 11/21] custom cpu models: avoid redundant config load

[Arthur Bied-Charreton <a.bied-charreton@proxmox.com>]

get_custom_model unconditionally loads the custom CPU models config. In
order to allow avoiding a redundant load at a call site that already has
the config loaded, take an optional $conf parameter and only load the
config if that is undefined.
