Build fails when CONFIG_CFG80211 is not enabled

Bug Description

When CONFIG_CFG80211 is disabled, the build fails with:

error: ‘struct net_device’ has no member named ‘ieee80211_ptr’

This happens because there is an undefined dependency for this kernel module: CONFIG_CFG80211.

Upstream Kconfig doesn't reflect that dependency:

config RTL8812AU
    tristate "Realtek 8812A USB WiFi"
    depends on USB

dkms should avoid building if the targetted kernel doesn't come with CONFIG_CFG80211 enabled.

For reference, this was seen while running ADT for linux-kvm, 5.19.0-1019.20.

Seen on jammy:linux-kvm 5.15.0-1029.34

It is not really the same error, but it is also caused by not checking if CONFIG_CFG80211 is enabled.
