Subject: [Patch 1/1] Segfault in ietd buffer overrun in dump_line

Fix a buffer overrun problem in __dump_line function in log.c file.
It also removes a stray 'return' call in log_pdu function which was
restricting a PDU dump call to complete log_pdu operation.

Also, in log_pdu function, the first check for log_level against
passed parameter for log was incorrect and would have forced a return
even when the caller has set the logging level to acceptable level.
