    vhost: fix mmap error check in VDUSE IOTLB miss handler
    
    The mmap() function returns MAP_FAILED on failure, not NULL.
    The current check for !mmap_addr will never detect mmap failures.
    
    When mmap fails but the error is not detected, an invalid address (-1)
    is inserted into the IOTLB cache via vhost_user_iotlb_cache_insert().
    Subsequent attempts to access this address will cause memory
    corruption or crash.
    
    Fix by checking for MAP_FAILED instead of NULL. Also add strerror to
    the error message for easier debugging.
