Subject: [PATCH v2 37/65] staging: wfx: simplify wfx_set_mcast_filter()

From: Jérôme Pouiller <jerome.pouiller@...abs.com>

HIF functions return only serious errors (OOM or device freeze). The
current handling of errors in wfx_set_mcast_filter() does not bring
anything. Finally it may disturb the developer more than it helps.
