i2c: xiic: Fix pm_runtime_set_suspended() with runtime pm enabled

Browse Source 
commit 0c8d604dea437b69a861479b413d629bc9b3da70 upstream.

It is not valid to call pm_runtime_set_suspended() for devices
with runtime PM enabled because it returns -EAGAIN if it is enabled
already and working. So, call pm_runtime_disable() before to fix it.
