Adjusts the section prefixes of some KVM x86 code function because with the monolithic KVM model the section checker can now do a more accurate static analysis at build time and it found a potentially kernel crashing bug. This also allows to build without CONFIG_SECTION_MISMATCH_WARN_ONLY=n. The __exit removed from machine_unsetup is because kvm_arch_hardware_unsetup() is called by kvm_init() which is in the __init section. It's not allowed to call a function located in the __exit section and dropped during the kernel link from the __init section or the kernel will crash if that call is made.
