x86/xen: Add call of speculative_store_bypass_ht_init() to PV paths
commit 74899d92e66663dc7671a8017b3146dcd4735f3b upstream.
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.
