misc: rtsx: set NULL intfdata when probe fails

[ Upstream commit f861d36e021e1ac4a0a2a1f6411d623809975d63 ]

rtsx_usb_probe() doesn't call usb_set_intfdata() to null out the
interface pointer when probe fails. This leaves a stale pointer.
Noticed the missing usb_set_intfdata() while debugging an unrelated
invalid DMA mapping problem.

Fix it with a call to usb_set_intfdata(..., NULL).
