Add two variables to store completion irq and event queue irq. And add
a new lable to free event queue irq in error path in gaudi2_enable_msix().
Fixes: d7bb1ac89b2f ("habanalabs: add gaudi2 asic-specific code")
Signed-off-by: Yang Yingliang <[email protected]>

v2:
print correct irq in error prints.
