From: Tom Rix <trix@redhat.com>
Subject: 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.
