uhid_snes: Remove USB_ST_TRANSFERRED handling for the status request.

The result of the request computed in new_status was never returned to
the caller leaving new_status as a set-but-unused variable. Removing
new_status leaves sc->previous_status as a write-only variable.
Removing sc->previous_status leaves current_status as a write-only
variable, so it collapses down to removing the entire
USB_ST_TRANSFERRED case.

Arguably, all of the support for UHID_SNES_STATUS_DT_RD should be
removed as it doesn't return anything to the caller. If the request
should be fixed instead then this commit should be reverted and
new_status should be returned to whoever submitted the request.

usb: real freebsd32 support for most ioctls

Use thunks or alternative access methods to support ioctls without
the COMPAT_32BIT hacks that store pointers in uint64_t's on 32-bit
platforms. This should allow a normal i386 libusb to work.

On CheriBSD, the sizes of the structs will differ between CheriABI
(the default) and freebsd64 no matter what so we need proper compat
support there. This change paves the way.
