mccmon6: Quote recovery_status in bootcmd test

The mccmon6 bootcmd starts with:

    if test -n ${recovery_status}; then run boot_recovery; ...

The default state is "no recovery requested", i.e. recovery_status
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 recovery.

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