[PATCH] obvious fix to dfp-bit.c (checked in)

[Janis Johnson]

In an earlier patch I inadvertently changed the rounding mode used for
DFP to INT conversions without noticing that I had broken them.  Tested
on powerpc64-linux and checked into mainline as obvious.

	* dfp-bit.c (DFP_TO_INT): Fix rounding mode.
