    libxl: correct bug in domain builder regarding page tables for pvh
    
    Commit 81a76e4b12961a9f54f5021809074196dfe6dbba ("libxc: rework of
    domain builder's page table handler") dropped a special case for pvh
    resulting in page tables being mapped read-only. This led to a panic
    of the domain in early boot.
    
    Correct this error.
