wifi: iwlwifi: remove 'use_tfh' config to fix crash
This is equivalent to 'gen2', and it was always confusing to have two identical config entries. The split config patch actually had been originally developed after removing 'use_tfh" and didn't add the use_tfh in the new configs as they'd later been copied to the new files. Thus the easiest way to fix the init crash here now is to just remove use_tfh (which is erroneously unset in most of the configs now) and use 'gen2' in the code instead. There's possibly still an unwind error in iwl_txq_gen2_init() as it crashes if TXQ 0 fails to initialize, but we can deal with it later since the original failure is due to the use_tfh confusion.
