Nikita Zhandarovich e6ef3a870b wifi: ar5523: enable proper endpoint verification 
[ Upstream commit e120b6388d7d88635d67dcae6483f39c37111850 ]

Syzkaller reports [1] hitting a warning about an endpoint in use
not having an expected type to it.

Fix the issue by checking for the existence of all proper
endpoints with their according types intact.

Sadly, this patch has not been tested on real hardware.

[1] Syzkaller report:
