common/main: support bootdelay=0 for CONFIG_AUTOBOOT_KEYED

Browse source 
Support bootdelay=0 in abortboot for the CONFIG_AUTOBOOT_KEYED case
similar to the CONFIG_ZERO_BOOTDELAY_CHECK support for the
!CONFIG_AUTOBOOT_KEYED case.

Do this by reversing the loop so we do at least one iteration before
checking for timeout.
