scsi: Have scsi_init_dev_desc_priv() use memset
When we do not have CONFIG_BOUNCE_BUFFER enabled, inside of
scsi_init_dev_desc_priv we never set the 'bb' field to false, we only
initialize it to true when CONFIG_BOUNCE_BUFFER is set. Given that we
have a number of other fields here we had been explicitly setting to
zero, change to first calling memset to clear the struct and then
initialize only the fields that need non-zero default values.
