ACPI: APEI: EINJ: Fix einj_dev release leak

Browse Source 
The platform driver conversion of EINJ mistakenly used
platform_device_del() to unwind platform_device_register_full() at
module exit. This leads to a small leak of one 'struct platform_device'
instance per module load/unload cycle. Switch to
platform_device_unregister() which performs both device_del() and final
put_device().
