mlxsw: spectrum_router: simplify list unwinding
[ Upstream commit 6f2f36e5f932c58e370bff79aba7f05963ea1c2a ]
The setting of i here
err_nexthop6_group_get:
i = nrt6;
Is redundant, i is already nrt6. So remove
this statement.
The for loop for the unwinding
err_rt6_create:
for (i--; i >= 0; i--) {
Is equivelent to
for (; i > 0; i--) {
Two consecutive labels can be reduced to one.
