Subject: [PATCH] net: ethernet: slicoss: remove redundant initialization of idx

From: Colin Ian King <colin.king@...onical.com>

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
