net: ipa: disable IEOB interrupts before clearing
Currently in gsi_isr_ieob(), event ring IEOB interrupts are disabled
one at a time. The loop disables the IEOB interrupt for all event
rings represented in the event mask. Instead, just disable them all
at once.
Disable them all *before* clearing the interrupt condition. This
guarantees we'll schedule NAPI for each event once, before another
IEOB interrupt could be signaled.
