Subject: [PATCH 56/65] staging: wfx: simplify wfx_suspend_resume_mc()

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

Indeed, it is not necessary to pass whole hif_ind_suspend_resume_tx to
wfx_suspend_resume_mc().

In add, the structure hif_ind_suspend_resume_tx come from hardware API.
It is not intended to be manipulated in upper layers of the driver.
