[SCSI] Fix printing of failed 32-byte commands
Having the large CDB allocation logic in sd.c means that
scsi_io_completion does not have access to the command buffer. That in
turn causes garbage to be printed when a 32-byte command fails. Move the
command printing to sd_done where the command buffer is intact. Clear
the command buffer pointer after the extended CDB has been freed.
Make scsi_print_command ignore commands with NULL CDB pointers to
inhibit printing of garbled command strings.
