RDMA/nldev: validate dynamic counter attribute length
RDMA_NLDEV_ATTR_STAT_HWCOUNTERS is a nested attribute whose children are
consumed directly with nla_get_u32(). The top-level policy validates only
the container, so it does not establish the fixed shape of each child.
Require every child payload to be exactly one u32 before reading it.
Fixes: 3c3c1f141639 ("RDMA/nldev: Allow optional-counter status configuration through RDMA netlink")
