…t mid-array (apache#1240)

`ReferenceCountedArrowArray.unsafeAssociateAllocation` calls `retain()`
before `wrapForeignAllocation`. If `wrapForeignAllocation` throws
(allocator over its limit), the retain is never balanced, the reference
count stays elevated, and the C Data release callback never fires —
leaking the producer's native memory.

**Fix:** call `retain()` after `wrapForeignAllocation` returns. Same
behavior on the success path; on failure the existing `finally` in
`ArrayImporter.importArray` drives the count to zero and fires the
release callback.

**Test:** `ImportOutOfMemoryTest` — exports a batch from a "producer"
allocator, tries to import it into a too-small consumer, and asserts the
producer drains to zero after the OOM. Fails on the original code,
passes with the fix.

Fixes: apache#1239
