thermal: msm_tsense: fix request irq ordering

Triggering an irq might cause an update to the thermal zone device.
If the thermal zone device is not initialized then a kernel panic ensues.
Request the irq after the thermal devices have been initialized, this way
the isr will be called only after it is initialized.
