Michael Ellerman d69f082cb8 selftests/powerpc: Fix error handling in FPU/VMX preemption tests 
BugLink: https://bugs.launchpad.net/bugs/2055075

[ Upstream commit 9dbd5927408c4a0707de73ae9dd9306b184e8fee ]

The FPU & VMX preemption tests do not check for errors returned by the
low-level asm routines, preempt_fpu() / preempt_vsx() respectively.
That means any register corruption detected by the asm routines does not
result in a test failure.

Fix it by returning the return value of the asm routines from the
pthread child routines.
