Update the signature of dn_dst_gc() to return void instead of int.

This change is required because the .gc member of struct dst_ops was
updated to a void return type in a previous commit [1]. This leads to the
following build error:

net/decnet/dn_route.c:132:10: error: initialization of 'void (*)(struct dst_ops *)' from incompatible pointer type 'int (*)(struct dst_ops *)' [-Werror=incompatible-pointer-types]

Note that dst_alloc() inside net/core/dst.c was already updated to
ignore the return value of this callback.
