accel/ivpu: Clear runtime_error after pm_runtime_resume_and_get() fails

Browse Source 
pm_runtime_resume_and_get() sets dev->power.runtime_error that causes
all subsequent pm_runtime_get_sync() calls to fail.
Clear the runtime_error using pm_runtime_set_suspended(), so the driver
doesn't have to be reloaded to recover when the NPU fails to boot during
runtime resume.
