Allow moving the wiphy device for mwififex to a non-inital network
namespace. Many wireless drivers enable this flag implicitly by
initializing through the generic ieee80211_alloc_hw_nm function. As
mwifiex does not utilize this function WIPHY_FLAG_NETNS_OK must be set
explicitly.

Moving to network namespace and working connection tested using
wpa_supplicant from a network namespace as well as from a container on
GyroidOS. The hardware was the Toradex Apalis i.MX8QM Board using the
Azurewave AW-CM276NF wireless module.
