On TDX it is possible for the untrusted host to cause
set_memory_encrypted() or set_memory_decrypted() to fail such that an
error is returned and the resulting memory is shared. Callers need to take
care to handle these errors to avoid returning decrypted (shared) memory to
the page allocator,

Shared (decrypted) pages should never return to the page allocator, or
future usage of the pages may allow for the contents to be exposed to the
host. They may also cause the guest to crash if the page is used in way
disallowed by HW (i.e. for executable code or as a page table).
