4.9-stable review patch. If anyone has any objections, please let me know.

From: Jiri Slaby <jslaby@suse.cz>

commit 6f17581788206444cbbcdbc107498f85e9765e3d upstream.

gcc 7 complains:
drivers/net/wireless/intersil/p54/fwio.c: In function 'p54_scan':
drivers/net/wireless/intersil/p54/fwio.c:491:4: warning: 'memset' used with length equal to number of elements without multiplication by element size [-Wmemset-elt-size]

Fix that by passing the correct size to memset.
