[PATCH] iwlwifi: mei: fix building iwlmei

Building iwlmei without CONFIG_CFG80211 causes a link-time warning:

ld.lld: error: undefined symbol: ieee80211_hdrlen
>>> referenced by net.c
>>> net/wireless/intel/iwlwifi/mei/net.o:(iwl_mei_tx_copy_to_csme) in archive drivers/built-in.a

Add an explicit dependency to avoid this. In theory it should not
be needed here, but it also seems pointless to allow IWLMEI
for configurations without CFG80211.

I see this warning on 5.17-rc8, but did not test it on linux-next,
which may already have a fix.
