Aleksandr Miloserdov 17c2c52051 scsi: target: core: Add cmd length set before cmd complete
[ Upstream commit 1c73e0c5e54d5f7d77f422a10b03ebe61eaed5ad ]

TCM doesn't properly handle underflow case for service actions. One way to
prevent it is to always complete command with
target_complete_cmd_with_length(), however it requires access to data_sg,
which is not always available.

This change introduces target_set_cmd_data_length() function which allows
to set command data length before completing it.
