Variable idx is being initialized and later on over-written by
a new value in a do-loop without the initial value ever being
read. Hence the initializion is redundant and can be removed.
Cleans up clang warning:

drivers/net/ethernet/alacritech/slicoss.c:358:15: warning: Value
stored to 'idx' during its initialization is never read

You should probably reorder the variables now so they stay longest to
shortest.

I agree. While the change itself is ok, it would be nice if
we could keep the order of the variables by length.
