brcm47xx: fix reading WGT634U CFE variables
We got check for nvram_len placed too early and the code never tried reading CFE variables used on WGT634U. This is a regression introduced in r45942 and reported in #20291. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Backport of r46584 git-svn-id: svn://svn.openwrt.org/openwrt/branches/chaos_calmer@46585 3c298f89-4303-0410-b956-a3cf2f4a3e73
