KVM: arm64: selftests: Improve error handling for GICv5 PPI selftest

Browse Source 
Cases where the KVM_RUN ioctl returned an error were wrongly reported
as incorrect ucalls. Furthermore, potential failures when calling
KVM_IRQ_LINE were being hidden.

Improve the error handling to correctly propagate the error in both
cases.
