init.hardware.rc: Improve I/O performance
It is known that I/O performance is suboptimal if the CFQ group_idle
parameter is not zero or if the BFQ slice_idle parameter is not zero.
Since Redbull devices use the CFQ I/O scheduler and since slice_idle is
a BFQ parameter, write 0 into the group_idle parameter.
