GBE: fix error in the rootn fastpath function for some special input.

The fastpath is to lose some accuracy but get fast speed. It is not
to generate error result. The rootn has many special input and need
to be taken care before we call the native pow directly.
This patch fix all the pow related failures at the OpenCV 3.0 test
suite.
