[PATCH 6/6] aristainetos2: Quote rescue_reason in rescueboot test

[Simon Glass]

The rescueboot script optionally runs a per-board rescue_reason hook
with:

    if test -n ${rescue_reason}; then run rescue_reason; fi;

The default state is "no rescue reason script", i.e. rescue_reason
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 run.

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

Fixes: 8b0619579b22 ("cmd: test: fix handling of single-argument form of test")
