x86/xen: Add call of speculative_store_bypass_ht_init() to PV paths
Commit: 1f50ddb4f418 ("x86/speculation: Handle HT correctly on AMD") ... added speculative_store_bypass_ht_init() to the per-CPU initialization sequence. speculative_store_bypass_ht_init() needs to be called on each CPU for PV guests, too.
