        src/sys/arch/powerpc/include: userret.h

Log Message:
When returning back to user mode, if the lwp has lost the FPU, not only
clear PSL_FP bit (to force a FPU Unavailable exception) but clear
PSL_FE0 and PSL_FE1 so that the FP execption mode is changes to ignore.
This will prevent spurious FP exceptions being made when the running lwp
doesn't own the FPU.
