Revert "iwlwifi: mvm: treat EAPOLs like mgmt frames wrt rate"
This reverts commit aa11bbf3df026d6b1c6b528bef634fd9de7c2619.
This commit was causing connection issues and is not needed
if IWL_MVM_RS_RSSI_BASED_INIT_RATE is set to false by default.
Regardless of the issues mentioned above, this patch added the
following WARNING:
