Commit a7b9020b06ec ("x86/l1tf: Handle EPT disabled state proper",
2018-07-13) dropped the "__exit" attribute from vmx_exit because
vmx_init was changed to call vmx_exit.

However, commit e32b120071ea (KVM: VMX: Do _all_ initialization
before exposing /dev/kvm to userspace, 2022-11-30) changed vmx_init
to call __vmx_exit instead of vmx_exit. This made it possible to
mark vmx_exit as "__exit" again, as it originally was, and enjoy
the benefits that it provides (the function can be discarded from
memory in situations where it cannot be called, like the module
being built-in or module unloading being disabled in the kernel).
