Idiom Recognition - fix bug in PPI_CUils
Bug #706483 "PPI_CUtils Idiom detection causing incorrect output"
The Idiom Recognition substitutes a function for the basic PPI 'Force
Gray' function which additionally turns off JPEG image passthrough while
this feature is in force. This was for bug #702964.
Unfortunately the substituted function was leaving the return values
from .putdeviceparamsonly on the stack, leading to incorrect output.
Just pop the returned values, we don't want them.
