kernel 3.8: routerstationpro: use KERNEL_IMAGE_MAXSIZE to test the image

routerstationpro is limited to 16mb flash size.  Exceeding that size may
not be noticed immediately, which we don't want.

"The current latest kernel for the routerstationpro machine is far
beyond the 16MB of it's flash size [0]. I think it would be good to
[test if the size of the image is above that size]."

Setting this variable will enable the do_sizecheck task and produce an
error when the image is too large:

"ERROR: This kernel (size=90230265 > 16777216) is too big for your
device. Please reduce the size of the kernel by making more of it
modular."
