Log more precise DCB write error messages

Browse Source 
The DCB error messages now log the type of the DCB and the remote address
in addition to the system error message. The file descriptor and memory
address are no longer printed in the error message as they are not useful
to the end user. The fd and address are now logged at debug level with a
more verbose error message.
