Matthew Maurer f6d8fea9e3 rust_binder: Avoid holding lock when dropping delivered_death ... In 6c37bebd8c, we switched to looping over the list and dropping each individual node, ostensibly without the lock held in the loop body. If the kernel were using Rust Edition 2024, the comment would be accurate, and the lock would not be held across the drop. However, the kernel is currently using 2021, so tail expression lifetime extension results in the lock being held across the drop. Explicitly binding the expression result to a variable makes the lockguard no longer part of a tail expression, causing the lock to be dropped before entering the loop body. This was detected via `CONFIG_PROVE_LOCKING` identifying an invalid wait context at the drop site.
