[PATCH 5/6] vcs: poll(): cope with a deallocated vt

When VT_DISALLOCATE is used on a vt, user space waiting with poll() on the corresponding /dev/vcs device is not awakened. This is now fixed by returning POLLHUP|POLLERR to user space. Also, in the normal screen update case, we don't set POLLERR anymore as POLLPRI alone is a much more logical
