Coding Standards: Remove unnecessary unset() calls in WP_Importer methods.

Browse Source 
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.
