machine: improve code style in get_pve_version

Browse Source 
This makes it a bit more obvious what happens and having an actual
error for bogus $PVE_MACHINE_VERSION entries.

Note that there was no auto-vivification before, as we never directly
accessed $PVE_MACHINE_VERSION->{$verstr}->{highest} but used
get_machine_pve_revisions to query a specific QEMU machine version's
PVE revisions and then operated on the return value, and that method
returns undef if there is no entry at all.
