cxl/hdm: Fix newline character in dev_err() messages

The newline character is not placed at the end of the string. This
causes unintended line wraps, broken log level and unterminated log
messages. Fix that for all messages.

Note that the messages are changed to use colons now instead of
parentheses, which is more common use.
