Sean Christopherson 09bb926d29 KVM: selftests: Return a value from vcpu_get_reg() instead of using an out-param
Return a uint64_t from vcpu_get_reg() instead of having the caller provide
a pointer to storage, as none of the vcpu_get_reg() usage in KVM selftests
accesses a register larger than 64 bits, and vcpu_set_reg() only accepts a
64-bit value.  If a use case comes along that needs to get a register that
is larger than 64 bits, then a utility can be added to assert success and
take a void pointer, but until then, forcing an out param yields ugly code
and prevents feeding the output of vcpu_get_reg() into vcpu_set_reg().
