Kirill A. Shutemov dc849d3e8f x86/mm: Allow guest.enc_status_change_prepare() to fail ...

[ Upstream commit 3f6819dd19 ]

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.
