[PATCH] i2c: s3c2410: resume race fix

[Doug Anderson <dianders-F7+t8E8rja9g9hUCZPvPmw@public.gmane.org>]

From: Olof Johansson <olof-nZhT3qVonbNeoWH0uzbU5w@public.gmane.org>

Don't unmark the device as suspended until after it's been re-setup.

The main race would be w.r.t. an i2c driver that gets resumed at the same
time (asyncronously), that is allowed to do a transfer since suspended
is set to 0 before reinit, but really should have seen the -EIO return
instead.
