fix return type of netif_add_ip6_address mismatch

Browse Source 
the netif_add_ip6_address function was declared err_t in
src/include/lwip/netif.h, but defined as s8_t (the default value of
err_t) in its implementation in src/core/netif.c.

this causes "conflicting types for 'netif_add_ip6_address'" errors if
err_t is defined differently in cc.h (as for example recommended in
[1]).

as it only returns error constants, it is changed to use err_t
throughout.
