RDMA/uverbs: Fix potential leak of resources->collection in flow_resources_alloc()

Browse source

The two array allocations are done unconditionally and only checked
afterwards, so if the counters allocation fails while the collection
allocation succeeds, the error path frees counters and the containing
struct but never frees resources->collection, losing the only pointer
to it.
