--------------------------------

This reverts commit 7959a47042a6c1ec5a97966cf3c04ee972b55348.

Commit 2fe0e281f7ad (cifs: fix double free race when mount fails in cifs_get_root()) fixes a double free. However there is no such issue on 4.19 because it will return after cifs_cleanup_volume_info().

Since merge this patch, cifs_cleanup_volume_info() is skipped, leading to a memory leak.
