[PATCH 07/16] staging: wfx: field operational_rate_set is ignored by firmware

[Jerome Pouiller]

From: JÃrÃme Pouiller <jerome.pouiller@xxxxxxxxxx>

The field bss_params.operational_rate_set is ignore by the firmware. It
is not necessary to send it. This change greatly simplify
wfx_join_finalize(). It is no more necessary to get sta and it allow to
save a RCU.
