[make-initrd] [PATCH 3/3] feature/kickstart: Reset rootdelay timer after kickstart

[Alexey Gladkov]

If the rootdelay timer has started counting down, then after poll is
unpaused, a timeout may occur. This is because the rootdelay remembers
the time and if the kickstart took a long time it will timeout the next
time the rootdelay is checked.

To avoid this we reset the timer before we unpause poll.
