ixp4xx: Don't overwrite memory in wg302v1_fixup()
wg302v1_fixup() looks for the ATAG_CMDLINE atag, it doesn't find it and so it takes the last atag in the list and overwrites non allocated memory. The side effects are corrupted vital data and a kernel that doesn't boot. More details here https://dev.openwrt.org/ticket/18356 The fix appends the fixup to the command line and updates the atag only when it finds it.
