Remove the !ch->target tests from the reconnect code. These tests are not needed: upon entry of srp_rport_reconnect() it is guaranteed that all ch->target pointers are non-NULL. None of the functions srp_new_cm_id(), srp_finish_req(), srp_create_ch_ib() nor srp_connect_ch() modifies this pointer. srp_free_ch_ib() is never called concurrently with srp_rport_reconnect().
