Tom Rix 45779b036d mm: initialize return of vm_insert_pages ...

clang static analysis reports a garbage return

  In file included from mm/memory.c:84:
  mm/memory.c:1612:2: warning: Undefined or garbage value returned to caller [core.uninitialized.UndefReturn]
          return err;
          ^~~~~~~~~~

The setting of err depends on a loop executing.  So initialize err.
