        src/sys/arch/i386/i386: trap.c

Log Message:
Remove the splurious check for EN_SW_DATACHAIN when looking at mxcsr traps.
The relevant bit is always masked out higher up.
The only place I can find a reference to a 'datachain' error is for the
  weitek 1167 fpu. Even the 8087 has the corresponding bit of the x87
  status reserved.
Quite why it has appeared here is anybodies guess.
