    libxl: Fix the bug introduced in commit "libxl: use correct type modifier 
for vuart_gfn"
    
    In libxl__device_vuart_add vuart_gfn is getting stored as a hex value:
    
    > flexarray_append(ro_front, GCSPRINTF("%"PRI_xen_pfn, state->vuart_gfn));
    
    However, xenstore reads this value as a decimal value and tries to map the
    wrong address and fails.
    
    This patch introduces a new format specifier "PRIu_xen_pfn" which formats 
the value as a
    decimal value.
