Luiz Otavio O Souza 1210d2685f Fix cpsw_detach() to not panic when called from cpsw_attach(). ... For an unkown reason (at moment), sometimes if_cpsw cannot read from PHY and fails to attach calling cpsw_detach() which end up in a panic. Fix it by doing the proper check before detach the miibus and also fix the leak of few variables. And to actually make it work, ether_ifattach() has to be moved to the end of cpsw_attach() to avoid a race where calling ether_ifdetach() before domain_init() (which will only run later on) would make it crash at INP_INFO_RLOCK() on in_pcbpurgeif0().
