[SCSI] qla2xxx: Do not take a second firmware dump when intentionally generating one. 

When we are intentionally generating a firmware dump by executing the
MBC_GEN_SYSTEM_ERROR command, the command actually times out. The normal
course of action when a mailbox command times out is to take a firmware dump.
However, in this special case we do not want to do this since the
MBA_SYSTEM_ERR AEN already generates a firmware dump.
