   ### Describe the bug, including details regarding any error messages, 
version, and platform.
   
   When importing a C Data array into a BufferAllocator that hits its limit 
part-way through a multi-buffer array, the producer's native memory leaks 
permanently.
   
   The bug is in 
[ReferenceCountedArrowArray.unsafeAssociateAllocation](https://github.com/apache/arrow-java/blob/main/c/src/main/java/org/apache/arrow/c/ReferenceCountedArrowArray.java#L67):
 it increments the reference count before calling wrapForeignAllocation. If 
wrapForeignAllocation throws (allocator over limit), **nothing decrements that 
count**, so the C Data release callback never fires.
   
   **Fix**: move `retain()` to after wrapForeignAllocation succeeds.
