platform/x86: x86-android-tablets: Stop using EPROBE_DEFER

Since the x86-android-tablets code uses platform_create_bundle() it cannot
use EPROBE_DEFER and the driver-core will translate EPROBE_DEFER to ENXIO.

Stop using EPROBE_DEFER instead log an error and return ENODEV, or for
non-fatal cases log a warning and return 0.
