[PATCH v2] i3c: master: svc: Fix pm_runtime_set_suspended() with runtime pm enabled

[Jinjie Ruan]

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.
