[Xen-changelog] [xen master] tools/mce: remove extra newlines from xen-mceinj error message



commit 255bd21d187c2db0c7e8b798f5ebf21e0be5548b

    tools/mce: remove extra newlines from xen-mceinj error message
    
    err() calls perror() which appends a newline.
    
    Make Lprintf() also append a newline so err() and Lprintf() are
    consistent.
