[PATCH 5.14 200/849] most: fix control-message timeouts

From: Johan Hovold <johan@kernel.org>

commit 63b3e810eff65fb8587fcb26fa0b56802be12dcf upstream.

USB control-message timeouts are specified in milliseconds and should
specifically not vary with CONFIG_HZ.

Use the common control-message timeout defines for the five-second
timeouts.
