Alice Ryhl b9d17aa74d rust_binder: avoid allocating under node_refs for freeze listeners

The node_refs mutex needs to be changed to a spinlock, so in preparation
for that, update freeze.rs to avoid allocating under the node_refs lock.
This is done by adding a retry loop so that if add_freeze_listener()
requires reallocating the KVVec<_> of freeze listeners, the caller will
allocate a larger vector and retry.

Analogously, the remove_freeze_listener() function is updated to return
the empty KVVec<_> when it is no longer needed, to avoid calling
kvfree() under the node_refs lock.
