If sense_flags and fixed_valid are zero, the kernel does not need to
output a printk message. So, if those conditions are met, it just returns.

scsi_decode_sense_extras() is utterly weird, as it only decodes
tape-specific sense extras. Seeing that 'st' and 'osst' already
contains code to handle those cases we should remove this function
altogether, as it doesn't serve any purpose.
Has been removed with my next scsi logging update, so this patch is
not applicable anymore.
Cheers,
Hannes
