Subject: [PATCH] USB: f81232: switch to generic tiocmiwait

Switch to generic tiocmiwait rather than rely on a custom implementation
using racy interruptible_sleep_on().

Note that this driver is mostly stubbed out so neither version of
tiocmiwait will actually work until someone implements
f81232_update_line_status().
