[PATCH 03/16] staging: wfx: drop useless attribute 'bss_params'

[Jerome Pouiller]

From: JÃrÃme Pouiller <jerome.pouiller@xxxxxxxxxx>

Since wfx_bss_params_work() does not exist anymore, there is no more
reason to keep a copy of bss_params in struct wfx_dev. A local instance
in wfx_join_finalize() is sufficient.
