mediatek: make sure MMC is not busy before commencing sysupgrade
In case of the block device still being in use, re-reading the partition table fails. In that case, abort sysupgrade to avoid corrupting the just-written image because of wrong offsets caused by failure to re-read the partition table. Signed-off-by: Daniel Golle <daniel@makrotopia.org>
