    xen/arm: domain_build: Check return code of domain_vpl011_init
    
    We are assigning return code of domain_vpl011_init() to a variable
    without checking it for an error. Fix it.
    
    Fixes: 3580c8b2dfc3 ("xen/arm: if direct-map domain use native UART address 
and IRQ number for vPL011")
