cifs: Check for UTF-16 null codepoint in SFU symlink target location

Browse source

Check that read buffer of SFU symlink target location does not contain
UTF-16 null codepoint (via UniStrnlen() call) because Linux cannot process
symlink with null byte, it truncates everything in buffer after null byte.
