beaglev_fire: Quote no_of_overlays in design test

On beaglev_fire, design_overlays gates an overlay-application loop
on:

    if test -n ${no_of_overlays}; then ...

The default state is "no overlays", i.e. no_of_overlays unset. The
expression then expands to 'test -n' with no operand and relies on a
U-Boot 'test' quirk that treats a missing operand as false to skip
the loop.

Quote the variable so an unset no_of_overlays expands to 'test -n ""'
and the emptiness check is explicit.
