Work Description: adoroszlai commented on pull request #147: HDDS-2464.
Avoid unnecessary allocations for FileChannel.open call
URL: https://github.com/apache/hadoop-ozone/pull/147
## What changes were proposed in this pull request?
`ChunkUtils` calls `FileChannel#open(Path, OpenOption...)`. Vararg array
elements are then added to a new `HashSet` to be passed to
`FileChannel#open(Path, Set<? extends OpenOption>, FileAttribute<?>...)`. We
can call the latter directly instead.

## How was this patch tested?
Ran `TestChunkUtils`.
