powerpc/64s: Fix unrelocated interrupt trampoline address test
The recent commit got this test wrong, it declared the assembler
symbols the wrong way, and also used the wrong symbol name
(xxx_start rather than start_xxx, see asm/head-64.h).
Fixes: ccd477028a ("powerpc/64s: Fix HV NMI vs HV interrupt recoverability test")
