[Qemu-devel] [PATCH] hpet: remove unnecessary code from post_load callback

[Paolo Bonzini]

The flags are already specified on the command line, so it is not
necessary to get them back from the migration stream.  They should
be already equal on the source and destination machine, unless the
destination machine is configured incorrectly.
