PM / Hibernate: Enable usermodehelpers in hibernate() error path
commit 05b4877f6a4f1ba4952d1222213d262bf8c132b7 upstream.
If create_basic_memory_bitmaps() fails, usermodehelpers are not re-enabled
before returning. Fix this. And while at it, reword the goto labels so that
they look more meaningful.
