typo in update_bootloader.sh

Thanks @DanLipsitt , my bad on that one..

PS, i'm moving the bootloader update from the current form, to new debian package..

debian@bbb-pwr01-ser09:/opt/u-boot/bb-u-boot-am335x-evm$ ls -lha ./*
-rwxr-xr-x 1 root root  708 Feb 19 21:40 ./install.sh
-rw-r--r-- 1 root root  91K Feb 19 21:40 ./MLO

debian@bbb-pwr01-ser09:/opt/u-boot/bb-u-boot-am335x-evm$ cat install.sh 
#!/bin/bash

if ! id | grep -q root; then
    echo "must be run as root"
    exit
fi

wdir="/opt/u-boot/bb-u-boot-am335x-evm"

if [ -b /dev/mmcblk0 ] ; then
    echo "dd if=${wdir}/MLO of=/dev/mmcblk0 count=1 seek=1 bs=128k"
    dd if=${wdir}/MLO of=/dev/mmcblk0 count=1 seek=1 bs=128k
    echo "dd if=${wdir}/u-boot.img of=/dev/mmcblk0 count=2 seek=1 bs=384k"
    dd if=${wdir}/u-boot.img of=/dev/mmcblk0 count=2 seek=1 bs=384k
