[PATCH] fib: fix vector lookup

Vector lookup uses gather instructions which loads data in 4byte chunks. This could lead to out of bounds access at the end of the tbl24 in case of 1 or 2 byte entries if e.g. lookup is attempted for 255.255.255.255 in IPv4 case. This patch fixes potential out of bound access by gather instruction
