Subject: [PATCH] x86/paravirt: pv_ops isn't GPL only

Commit 5c83511bdb9832 ("x86/paravirt: Use a single ops structure")
introduced a regression for out-of-tree modules using spinlocks, as
pv_lock_ops was exported via EXPORT_SYMBOL(), while the new pv_ops
structure now containing the pv lock operations is exported via
EXPORT_SYMBOL_GPL().

Change that by using EXPORT_SYMBOL(pv_ops).

Fixes: 5c83511bdb9832 ("x86/paravirt: Use a single ops structure")
