Re: [PATCH V4 1/3] livepatch: remove 'struct completion finish' from klp_patch

The completion finish is just for waiting release of the klp_patch
object, then releases module refcnt. We can simply drop the module
refcnt in the kobject release handler of klp_patch.

This way also helps to support allocating klp_patch from heap.
