x86/traps: Disentangle the 32-bit and 64-bit doublefault code
The 64-bit doublefault handler is much nicer than the 32-bit one. As a first step toward unifying them, make the 64-bit handler self-contained. This should have no effect no functional effect except in the odd case of x86_64 with CONFIG_DOUBLEFAULT=n in which case it will change the logging a bit. This also gets rid of CONFIG_DOUBLEFAULT configurability on 64-bit kernels. It didn't do anything useful -- CONFIG_DOUBLEFAULT=n didn't actually disable doublefault handling on x86_64.
