Subject: [PATCH 4/7] staging: wfx: correctly cast data on big-endian targets

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

When built for a big-endian target, original code caused error:

    include/uapi/linux/swab.h:242:29: note: expected '__u32 * {aka unsigned int *}' but argument is of type 'struct hif_mib_protected_mgmt_policy *'

Fixes: f95a29d40782 ("staging: wfx: add HIF commands helpers")
