msm: ipa: Fix the force_coals command stuck issue on AP suspend

IPA force_coals command stuck due to not getting the gsi interrupt.
The suspend on IPA AP/RMNET_IPA driver was registered as noirq type,
gsi interrupt handler won't be called because of this.
The fix is to change the suspend cb from suspend_noirq to suspend.
