vt_ioctl: change VT_RESIZEX ioctl to check for error return from vc_resize()
commit bc5269ca765057a1b762e79a1cfd267cd7bf1c46 upstream.
vc_resize() can return with an error after failure. Change VT_RESIZEX ioctl
to save struct vc_data values that are modified and restore the original
values in case of error.
