[PATCH 5/9] staging: r8188eu: use kernel helper to iterate over a list

[Martin Kaiser <martin@kaiser.cx>]

rtw_free_xmitframe_list iterates over the list of xmit_frames and frees
each entry. We can use list_for_each_entry_safe instead of coding this
manually. We need the _safe version as the current pxmitframe will be
removed from the list by rtw_free_xmitframe.
