wireless-drivers fixes for 4.17 

A few fixes for 4.17 but nothing really special. The new ETSI WMM
 parameter support for iwlwifi is not technically a bugfix but
 important for regulatory compliance.
 
 iwlwifi
 
 * use new ETSI WMM parameters from regulatory database
 
 * fix a regression with the older firmware API 31 (eg. 31.560484.0)
 
 brcmfmac
 
 * fix a double free in nvmam loading fails
 
 rtlwifi
 
 * yet another fix for ant_sel module parameter
