Subject: [PATCH] Coding Standards: Remove unnecessary `unset()` calls in
 `WP_Importer` methods.

Variables created within the scope of a function are discarded automatically when PHP leaves the scope of the function, i.e. on `return`, so doing a call to `unset()` straight before a `return` statement is redundant.

Props jrf, ravipatel, rachelbaker, mukesh27.
Fixes #52996.
