cxgb4: IEEE fixes for DCBx state machine
* Changes required due to 16eecd9be4b05 ("dcbnl : Fix misleading
dcb_app->priority explanation")
* Driver was previously not aware of what DCBx version was negotiated by
firmware, this could lead to DCB app table in kernel or in firmware being
populated wrong since IEEE/CEE used different formats made clear by above
mentioned commit
* Driver was missing a couple of state transitions that could be caused
by other drivers that use chelsio hardware, resulting in incorrect behaviour
(the change that addresses this also flips the state machine to switch on
state instead of transition, hope this is okay in current window)
* Prio queue info & tsa is no longer thrown away
v2: Print DCBx state transition messages only when debug is enabled
