msm: ipa3: Fix to processing of GSI IRQ when IPA is clock gated

When suspend IRQ is received from IPA HW, IPA clocks are voted on
and suspend IRQ handling is deferred and clocks are voted off.
When IPA clocks are voted on, end point suspend is removed on
WAN_CONS and LAN_CONS pipes. There is a possibility that between
clock voting on and off, GSI IRQ is raised and is tried to be
processed which results in a NOC error. Make a change to not
to defer processing of suspend IRQ to keep the IPA clock on
till GSI IRQ is processed.
