Apart from moving and adapting two places where $MAX_SATA_DISKS is used,
the initialization for the drive keys in $confdesc is changed
to be a single for-loop iterating over the keys of $drivedesc_hash.
To avoid the need to change all the call sites, the functions are
exported from the submodule and imported into QemuServer.pm.
