ftrace: Do not add duplicate entries in subops manager ops
commit 8eb4b09e0bbd30981305643229fe7640ad41b667 upstream.
Check if a function is already in the manager ops of a subops. A manager
ops contains multiple subops, and if two or more subops are tracing the
same function, the manager ops only needs a single entry in its hash.
