[Qemu-devel] [PULL 2/2] vnc: Wrap vnc initialization code with CONFIG_VNC

[Eduardo Habkost]

From: Chao Peng <address@hidden>

commit f8c75b2486 (vnc: Initialization stubs) removed CONFIG_VNC in vl.c
code. However qemu_find_opts("vnc") is NULL when vnc is configured out.
Crash will happen in qemu_opts_foreach() before stub vnc_init_func() is
called. This patch add it back.
