mount.cifs: check for invalid characters in device name and mountpoint
It's apparently possible to corrupt the mtab if you pass embedded
newlines to addmntent. Apparently tabs are also a problem with certain
earlier glibc versions. Backslashes are also a minor issue apparently,
but we can't reasonably filter those.
Make sure that neither the devname or mountpoint contain any problematic
characters before allowing the mount to proceed.
