iwlwifi enabling IBSS (Ad-Hoc) mode
This patch enables ibss mode. It consists of two changes upon entering ibss mode: 1. Removing the redundant line which clears the driver's station table. This line creates a discrepancy between the driver and the FW's station table. This prevented the generation of beacons. 2. Assigning a default value to priv's assoc_id. Normally given by an AP in STA mode, this field is used as an indication for association. Being 0, it prevented normal TX flow. 3. Remove a redundant ADD_STA command that cause uCode error. 4. Delay the set_mode until after the uCode is ready.
