[Qemu-devel] [PULL 1/5] vfio/pci: Fix VGA quirks

[Alex Williamson]

Commit 2d82f8a3cdb2 ("vfio/pci: Convert all MemoryRegion to dynamic
alloc and consistent functions") converted VFIOPCIDevice.vga to be
dynamically allocted, negating the need for VFIOPCIDevice.has_vga.
Unfortunately not all of the has_vga users were converted, nor was
the field removed from the structure.  Correct these oversights.
