[PATCH 3/5] cleanup ioengine_load() (for the next commit)

[kusumi.tomohiro@xxxxxxxxx]

From: Tomohiro Kusumi <tkusumi@xxxxxxxxxx>

This commit removes name argument from ioengine_load(), as both
ioengine name and path are self contained in td.
No functional changes.

This makes the next commit's diff more clear by separating non
functional noise.
