ar71xx: qihoo-c301: reset imageNtrynum after each successful boot.
Qihoo C301 has 2 flash chips of which one is used as primary and the
other is used as backup. OEM U-Boot will try to boot an activeregion N
with imageNstatus=0 and imageNtrynum <= imagemaxtry. If such a region
is found, bootloader will try to increment imageNtrynum and boot it.
This patch tries to reset imageNtrynum after each successful boot (if
the boot process reaches the execution of /etc/init.d/done).
