[Qemu-devel] [BUGFIX][PATCH for 2.2 1/1] hw/i386/pc_piix.c: Also pass vmport=off for xenfv machine

[Don Slutz <dslutz@verizon.com>]

c/s 9b23cfb76b3a5e9eb5cc899eaf2f46bc46d33ba4

or

c/s b154537ad07598377ebf98252fb7d2aff127983b

moved the testing of xen_enabled() from pc_init1() to
pc_machine_initfn().

xen_enabled() does not return the correct value in
pc_machine_initfn() so add vmport=off to xenfv machine to correctly
turn off vmport for xen.

Drop the call to xen_enabled() in pc_machine_initfn() to reduce
potential confusion.

The 1st version of "-machine vmport=off: Allow..." patch did not
have this issue.  It was the adjusting to the QOM that introduced
it.
