Make gdk_visual_get_*_pixel_details work again

These functions are supposed to return the numbers of consecutive
1 bits in each components mask as precision. However, due to a
copy-paste mistake when this code was moved around in
commit 70d689cddda0dc616af97e8ed047d0c0acf7c7a6, the precision
was always reported as zero. This affects only a few applications
that directly set window background on X11 windows, such as emacs.
