staging: rtl8723bs: fix null dereference in find_network
[ Upstream commit 41460a19654c32d39fd0e3a3671cd8d4b7b8479f ]
The variable pwlan has the possibility of being NULL when passed into
rtw_free_network_nolock() which would later dereference the variable.
Fixes: 554c0a3abf21 ("staging: Add rtl8723bs sdio wifi driver")
