This reverts commit 34226b6b70.
Commit 8990cac6e5 ("x86/jump_label: Initialize static branching
early") adds jump_label_init() call in setup_arch() to make static
keys initialized early, so we could use the original simpler code
again.
The similar change for XEN is in commit 090d54bcbc ("Revert
"x86/paravirt: Set up the virt_spin_lock_key after static keys get
initialized"")
