kexec: Use error path if crash region range can't be accessed

Although the error handling path in xen_machine_kexec_setup_resource()
is somewhat minmal, it ought to be used if HYPERVISOR_kexec_op() fails
whengetting the crash kernel region, as this indicates that an error
occured, not that the crash kernel region is empty.
