firmware: smccc: Fix use of uninitialised results structure
Commit 35727af2b15d ("irqchip/gicv3: Workaround for NVIDIA erratum
T241-FABRIC-4") moved the initialisation of the SoC version to
arm_smccc_version_init() but forgot to update the results structure
and it's usage.
Fix the use of the uninitialised results structure and update the
error strings.
