- specific con->error_msg messages (e.g. "protocol version mismatch")
end up getting overwritten by a catch-all "socket error on read
/ write", introduced in commit 3a140a0d5c ("libceph: report socket
read/write error message")
- "bad message sequence # for incoming message" loses to "bad crc" due
to the fact that -EBADMSG is used for both
Fix it, and tidy up con->error_msg assignments and pr_errs while at it.
