USB: PHY: msm: Fix pm_runtime race with sm_work during boot-up

If there is any ID line change during suspend, msm_otg_irq is called
for ID status and calling  msm_otg_resume to resume the HW out of LPM
from interrupt context and disable the async_irq. This may race with
another PM runtime msm_otg_resume from android_probe context and
disable async_irq again. After this as async_irq remains disable,
OTG irq handler never called on device connect/disconnect. This
results in device detection issues on bootup with host cable
connected. Fix this by improving PM runtime handling in sm_work.
