Subject: [PATCH 08/18] staging: lustre: hsm: copy start error should set HP_FLAG_COMPLETED

From: Aurelien Degremont <aurelien.degremont@....fr>

If an error occurs when initializing a HSM request, in
ll_ioc_copy_start(), the PROGRESS message, sent to coordinator, should
carry the error code but also HP_FLAG_COMPLETED to mark the request as
finished (with error). If not, the Coordinator will ignore this
message and consider the request is still running.
