Currently any further write requests after a timeout would fail after triggering a WARN() in usb_submit_urb() when attempting to submit the already active URB.

We are trying to let them use our new kernel font descriptor, `struct font_desc` instead. To make that work slightly easier, first delete all of their no-op implementations used by dummy consoles. This will make KD_FONT_OP_SET and KD_FONT_OP_SET_DEFAULT ioctl() requests on dummy consoles start to fail and return `-ENOSYS`, which is intended, since no user should ever expect such operations to succeed on dummy consoles.

Delete all the con_font_copy() callbacks, since we no longer use them. Mark KD_FONT_OP_COPY as "obsolete" in include/uapi/linux/kd.h, just like what we have done for PPPIOCDETACH in commit af8d3c7c001a ("ppp: remove the PPPIOCDETACH ioctl").

If runtime of the device has error or device is in inaccessible state(or other error state), resume operation will fail. If we do not call put operation to decrease the reference, the result is that this device cannot enter the idle state and always stay busy or other non-idle state.
