[PATCH 4.4 013/162] ALSA: line6: fix control and interrupt message timeouts

From: Johan Hovold <johan@kernel.org>

commit f4000b58b64344871d7b27c05e73932f137cfef6 upstream.

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

Fixes: 705ececd1c60 ("Staging: add line6 usb driver")
