Emmanuel Grumbach 2aabdbdc17 iwlwifi: pcie: enable interrupts before releasing the NIC's CPU 
The NIC's CPU gets started after the firmware has been
written to its memory. The first thing it does is to
send an interrupt to let the driver know that it is
running. In order to get that interrupt, the driver needs
to make sure it is not masked. Of course, the interrupt
needs to be enabled in the driver before the CPU starts to
run.
I mistakenly inversed those two steps leading to races
which prevented the driver from getting the alive interrupt
from the firmware.
Fix that.
