[SCSI] bnx2i : Fix "cid #n not valid" issue

When bnx2i_adapter_ready() fails, connection handle(cid) = 0 is wrongly freed
because 'cid' is not yet allocated for the endpoint.  Fix is to initialize
bnx2i_ep->ep_iscsi_cid to '-1' in bnx2i_alloc_ep() and not in
bnx2i_ep_connect() to avoid releasing invalid 'cid'.  There is already a check
in bnx2i_free_iscsi_cid() not to free invalid iscsi connection handle (-1)
