[Qemu-devel] [PATCH 2/2] Fix return value of vga initlization on ppc

[Mark Wu <wudxw@linux.vnet.ibm.com>]

Before spapr_vga_init will returned false if the vga is specified by
the command '-device VGA' because vga_interface_type was evaluated to
VGA_NONE. With the change in previous patch of this series,
spapr_vga_init should return true if it's told that the vga will be
initialized in flow of the generic devices initialization.

This patch also makes two cleanups:
1. skip initialization for VGA_NONE
2. remove the useless 'break'
