[PATCH] wifi: rtw89: drop redundant device reference

[Johan Hovold <johan@kernel.org>]

Driver core holds a reference to the USB interface and its parent USB
device while the interface is bound to a driver and there is no need to
take additional references unless the structures are needed after
disconnect.

Drop the redundant device reference to reduce cargo culting, make it
easier to spot drivers where an extra reference is needed, and reduce
the risk of memory leaks when drivers fail to release it.

Here's a follow-up to 

	https://lore.kernel.org/all/20260306085144.12064-1-johan@kernel.org/

which failed to include rtw89 despite Ping-Ke's explicit request (I
thought I had grepped for usb_get_dev in wireless before sending out
that series, but apparently not).
