mac80211: remove vif debugfs driver callbacks 

This basically reverts commit b207cdb07f.

Now is possible to use drv_{add,remove}_interface() and vif->debugfs_dir
to create/remove per interface debugfs files. Remove redundant
callbacks.

* @remove_interface_debugfs: Remove the debugfs files which were added using
* @add_interface_debugfs. This callback must remove all debugfs entries
* that were added because mac80211 only removes interface debugfs when the
