Subject: [PATCH][next] rtlwifi: rtl8192de: Fix uninitialized variable place

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

In the case where chnl <= 14 variable place is not initialized and
the function returns an uninitialized value. This fixes an earlier
cleanup where I introduced this bug. My bad.

Addresses-Coverity: ("Uninitialized scalar variable")
Fixes: 369956ae5720 ("rtlwifi: rtl8192de: Remove redundant variable initializations")
