USB: mos7720: fix broken control requests

commit ef6c8c1d733e244f0499035be0dabe1f4ed98c6f upstream.

The parallel-port code of the drivers used a stack allocated
control-request buffer for asynchronous (and possibly deferred) control
requests. This not only violates the no-DMA-from-stack requirement but
could also lead to corrupt control requests being submitted.
