intel: Fix stack overflow in intel_dump_gpu

intel: Fix stack overflow in intel_dump_gpu

Previously, the call to ensure_device_info in the intercepted ioctl
would eventually result in another call to ioctl, recursing until stack
overflow:

 - ioctl (intercepted)
 - ensure_device_info
 - intel_get_device_info_from_fd
 - intel_device_info_i915_get_info_from_fd
 - getparam
 - intel_ioctl
 - ioctl (intercepted)
