When an error occurs in Tx, and it is moved to ERROR state, it
is not recoverable, during recovery it's state cannot be modified
to INIT. to modify state from RESET to INIT, the port must be
passed in modify attributes, and in case of ERROR to READY
modification path, it was not provided.
Provide port number when changing state from RESET to INIT.
