[PATCH] shared compression workspaces limits doesnot match

In function find_workspace, it's allowed to alloc cpus + 1 workspaces at most,
but in function free_workspace, it will freed the workspace if there
exists more then cpus' workspaces.

The two limits doesn't match. I thought the original itention is
allowed to alloc
cpus compression workspaces at most.
