Subject: net: qrtr: Fix passing invalid reference to qrtr_local_enqueue()
Git-commit: d28ea1fbbf437054ef339afec241019f2c4e2bb6
Patch-mainline: 5.7-rc7
References: networking-stable-20_05_27

Once the traversal of the list is completed with list_for_each_entry(),
the iterator (node) will point to an invalid object. So passing this to
qrtr_local_enqueue() which is outside of the iterator block is erroneous
eventhough the object is not used.

So fix this by passing NULL to qrtr_local_enqueue().
