net/ncsi: Improve general state logging

commit 9ef8690be13d8ae3130749fbcc0cc21e4e3f738c upstream.

The NCSI driver is mostly silent which becomes a headache when trying to
determine what has occurred on the NCSI connection. This adds additional
logging in a few key areas such as state transitions and calling out
certain errors more visibly.
