x86/kernel: Mark the .bss..decrypted section as shared in the RMP table
The encryption attribute for the .bss..decrypted section is cleared in the
initial page table build. This is because the section contains the data
that need to be shared between the guest and the hypervisor.
When SEV-SNP is active, just clearing the encryption attribute in the
page table is not enough. The page state needs to be updated in the RMP
table.
