With the fence accounting fixed up in the previous commit not finding enough fences is a fatal error and userspace bug. Trashing the entire gtt is not gonna turn up that missing fence, so don't to this by returning another error thatn ENOSPC. This has the added benefit that it's easier to distinguish fence accounting errors from gtt space accounting issues. TTM serves as precendence for the EDEADLK error code - it returns it when the reservation code needs resources already blocked by the current reservation.
