Subject: [PATCH] zd1201: remove unused variable framelen

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

Variable framelen is assigned but never read, hence it is redundant
and can be removed. Cleans up clang warning:

drivers/net/wireless/zydas/zd1201.c:234:3: warning: Value stored
to 'framelen' is never read
