connect.c: improve comment in reconnect code that we ONLY requeue SCSI COMMAND

Browse Source 
The only PDU type that does not have ISCSI_PDU_DROP_ON_RECONNECT is the
SCSI COMMAND PDU. Thsi is the only PDU that we re-queue on reconnect.
All other, including DATA-OUT, NOP, task management, PDUs are simply
dropped.
