Bug Description

[Impact]

* Google requested fix to notify_range_enc_status_changed() passing incorrect argument.

[Fix]

* Upstream ac3f9c9f1b37 introduced change to notify_range_enc_status_changed() to accept page size instead of number of pages, but function was not updated. Updating to send correct argument. Upstream implementation changed with TDX
support, and is unaffected, so no plans to upstream.

[Test Case]

* Compile tested
* Boot tested
* Tested by Google

[Where things could go wrong]

* Low chance of regression. Isolated logic fix.

[Other Info]

* SF #00367134

This bug is awaiting verification that the linux-gcp/5.15.0-1047.55 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-jammy-linux-gcp' to 'verification-done-jammy-linux-gcp'. If the problem still exists, change the tag 'verification-needed-jammy-linux-gcp' to 'verification-failed-jammy-linux-gcp'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
