sfxge(4): ensure EvQ poll stops when abort is requested
If an event handler requested an abort, only the inner loop was
guarenteed to be broken out of - the outer loop could continue
if total == batch.
Fix this by poisoning batch to ensure it is different to total.

sfxge(4): add accessor to whole link status
Add a function which makes an MCDI GET_LINK request and
packages up the results. Currently, the get-link function
is triggered from several entry points which then pass
on or store selected parts of the data. When the driver
needs to obtain the current link state, it is more
efficient to do this in a single call.
