Makes sense to me,

Add compression `workspace' in free_workspace() to
`idle_workspace' list head, instead of tail. So we have
better chances to reuse most recently used `workspace'.

Hello,
Whenever possible, find_workspace() returns the first idle workspace;
and free_workspace() puts workspace to idle list tail. Put workspace to
head of idle list instead. Hopefully, this will let to reuse most recently
used workspace and avoid workspace->mem, ->buf, ->cbuf address translation
