[PATCH v3 28/41] x86/paravirt: Mark __paravirt_set_sched_clock() as __init

[Sean Christopherson <seanjc@xxxxxxxxxx>]

Annotate __paravirt_set_sched_clock() as __init, and make its wrapper
__always_inline to ensure sanitizers don't result in a non-inline version
hanging around.  All callers run during __init, and changing sched_clock
after boot would be all kinds of crazy.

No functional change intended.
