moxart: fix potential use-after-free on remove path
commit bd2db32e7c3e35bd4d9b8bbff689434a50893546 upstream.
It was reported that the mmc host structure could be accessed after it
was freed in moxart_remove(), so fix this by saving the base register of
the device and using it instead of the pointer dereference.
