accel/ivpu: Clear runtime_error after pm_runtime_resume_and_get() fails 



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.

Fixes: 7d4b4c74 ("accel/ivpu: Remove suspend_reschedule_counter")
