Andrew Scull fa81b25ab1 KVM: arm64: Stop clobbering x0 for HVC_SOFT_RESTART 
commit b9e10d4a6c upstream.

HVC_SOFT_RESTART is given values for x0-2 that it should installed
before exiting to the new address so should not set x0 to stub HVC
success or failure code.

Fixes: af42f20480 ("arm64: hyp-stub: Zero x0 on successful stub handling")
