Do not process any SCSI and IOCTL command further(return them with appropriate
return values to callers),
while driver removal is in progress/PCI shutdown is invoked.

scsi_log_send() would display buffer pointer for higher
logging levels. This is not only of questionable value
but also exposes kernel pointer to userspace, which is
discouraged in some setups. So drop this message

Use an external buffer for __scsi_print_command() and
move command logging over to use the per-cpu logging
buffer. With that we can guarantee the command always

So we can even print out a variable length command
correctly across several lines.
Finally rename
SPC-3 defines SERVICE ACTION IN(12), SERVICE_ACTION OUT(12),

And READ MEDIA SERIAL NUMBER has long since been deprecated.
So update callers to refer to the new cdb name.

Instead of having constants.c littered with ifdef statements
we should be moving dummy functions into the header and
condintionally compile in constants.c if selected.
And update the Kconfig description to reflect the
actual size difference.
