iwlwifi: mvm: Correctly set IGTK for AP
[ Upstream commit e829b17caf96c2da34620e335fb777592990906c ]
Currently when an IGTK is set for an AP, it is set as a regular key.
Since the cipher is set to CMAC, the STA_KEY_FLG_EXT flag is added to
the host command, which causes assert 0x253D on NICs that do not support
this.
