Sean Bruno bd84f70044 iflib:
Add internal tracking of smp startup status to reliably figure out
     what methods are to be used to get gtaskqueue up and running.

e1000:
     Calculating this pointer gives undefined behaviour when (last == -1)
     (it is before the buffer).  The pointer is always followed.  Panics
     occurred when it points to an unmapped page.  Otherwise, the pointed-to
     garbage tends to not have the E1000_TXD_STAT_DD bit set in it, so in the
     broken case the loop was usually null and the function just returned, and
     this was acidentally correct.
