rocker: fix maybe-uninitialized warning
In some rare configurations, we get a warning about the 'index' variable being used without an initialization: drivers/net/ethernet/rocker/rocker_ofdpa.c: In function ‘ofdpa_port_fib_ipv4.isra.16.constprop’: drivers/net/ethernet/rocker/rocker_ofdpa.c:2425:92: warning: ‘index’ may be used uninitialized in this function [-Wmaybe-uninitialized] This is a false positive, the logic is just a bit too complex for gcc to follow here. Moving the intialization of 'index' a little further down makes it clear to gcc that the function always returns an error if it is not initialized.
