[ALSA] Fix-up sleeping in sound/usb
USB generic driver,USB USX2Y Description: Fix-up sleeping in sound/usb. Replace big_mdelay() with msleep() to guarantee the task delays as expected. This also involved replacing/removing custom sleep functions. Patch is compile-tested. Signed-off-by: Nishanth Aravamudan <nacc@us.ibm.com> Signed-off-by: Jaroslav Kysela <perex@suse.cz>
