[PATCH] ltq-vdsl-vr9: fix upstream MINEFTR

[Jan Hoffmann]

The upstream value read from the device seems to already be in bits per
second, so there is no need to multiply by 1000 again (which for typical
values causes an overflow of the 32-bit unsigned integer).

This patch is already applied for ltq-vdsl-vr11. It is not relevant for
ltq-adsl, as G.INP in upstream direction is only supported for VDSl2.

I tested on my own DTAG VDSL2 line, and it works here (upstream MINEFTR
is now close to the upstream data rate).
