x86/realmode: Don't leak the trampoline kernel address
Since commit ad67b74d2469 ("printk: hash addresses printed with %p") at boot "____ptrval____" is printed instead of the trampoline addresses: Base memory trampoline at [(____ptrval____)] 99000 size 24576 Remove the print as we don't want to leak kernel addresses and this statement is not needed anymore.
