Eduardo Habkost 6b2699672d hostmem: Fix qemu_opt_get_bool() crash in host_memory_backend_init()
This fixes the following crash, introduced by commit
49d2e648e8087d154d8bf8b91f27c8e05e79d5a6:

  $ gdb --args qemu-system-x86_64 -machine pc,mem-merge=off -object memory-backend-ram,id=ram-node0,size=1024
  [...]
  Program received signal SIGABRT, Aborted.

Instead of using qemu_opt_get_bool(), that didn't work with
qemu_machine_opts for a long time, we can use the corresponding
MachineState fields.
