George Kennedy 7bed80bd03 vt_ioctl: change VT_RESIZEX ioctl to check for error return from vc_resize() ...

commit bc5269ca76 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.
