Subject: [PATCH][next] staging: wfx: fix swapped arguments in memset call

From: Colin Ian King <colin.king@...onical.com>

The memset appears to have the 2nd and 3rd arguments in the wrong
order, fix this by swapping these around into the correct order.

Addresses-Coverity: ("Memset fill truncated")
Fixes: 4f8b7fabb15d ("staging: wfx: allow to send commands to chip")
