Michael Ellerman 390da123c8 selftests/powerpc: Fix error handling in FPU/VMX preemption tests 
[ 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.

Fixes: e5ab8be68e44 ("selftests/powerpc: Test preservation of FPU and VMX regs across preemption")
