    riscv/vmm: Fix the build after a97f683fe3c4
    
    - Make machine/vmm_dev.h self-contained.
    - Check for errors from vmmdev_init().
    - Make VM_MAX_NAMELEN visible to userspace.
    
    Reported by:    Jenkins
    Fixes:  a97f683fe3c4 ("vmm: Add a device file interface for creating and 
destroying VMs")
