[PATCH] fastboot: avoid console_countdown_abort for getvar request

[Marco Felsch <m.felsch@pengutronix.de>]

Don't abort the console countdown in case of 'fastboot getvar' requests.
Most the time the host just want to query information but don't want to
abort the boot. Therefore skip the abort in case of getvar requests and
abort it in all other cases.
