Remove parallel-safety check from GetExistingLocalJoinPath.

Browse Source 
Commit a104a017fc has this check because
I added it to the submitted patch before commit, but that was entirely
wrongheaded, as explained to me by Ashutosh Bapat, who also wrote this
patch.

The function returns copy of a local join path, which can be converted
into an alternative local join plan, which may be useful when
implementing a <literal>RecheckForeignScan</> method. The function
searches for a parallel-safe, unparameterized path in the
<literal>pathlist</> of given <literal>joinrel</>. If it does not find
such a path, it returns NULL, in which case a foreign data wrapper may
build the local path by itself or may choose not to create access paths
for that join.
