Kirill A. Shutemov c598fefef3 x86/mm: Allow guest.enc_status_change_prepare() to fail 
[ Upstream commit 3f6819dd192ef4f0c568ec3e9d6d408b3fa1ad3d ]

TDX code is going to provide guest.enc_status_change_prepare() that is
able to fail. TDX will use the call to convert the GPA range from shared
to private. This operation can fail.

Add a way to return an error from the callback.
