scsi: qla2xxx: Silent erroneous message

Driver uses shadow pointer instead of Mirror pointer for firmware dump
collection. Skip those entries for Mirror pointers for Request/Response
queue from firmware dump template reading.

Following messages are printed in log messages:

 qla27xx_fwdt_entry_t268: unknown buffer 4
 qla27xx_fwdt_entry_t268: unknown buffer 5

This patch fixes these error messages by adding skip_entry() to not read
them from template.
