arm/arm64: paravirt: Remove GPL from pv_ops export

virt inclusion
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I4VZPC
CVE: NA

--------------------------------

Commit 63042c58 ("KVM: arm64: Add interface to support vCPU
preempted check") introduced paravirt spinlock operations, as pv_lock_ops
was exported via EXPORT_SYMBOL(), while the pv_ops structure containing
the pv lock operations is exported via EXPORT_SYMBOL_GPL().

Change that by using EXPORT_SYMBOL(pv_ops) for arm/arm64, as with the x86
architecture changes, the following:

check")
