wifi: nxpwifi: do not delete Rx reorder entries under RCU

Browse source

The RCU guard is declared in the body of the per-TID loop, so it is still
held across the teardown pass. nxpwifi_del_rx_reorder_entry() flushes the
Rx workqueue and deletes the reorder timer synchronously, both of which
sleep, so a station deauthenticating from the AP splats under
CONFIG_DEBUG_ATOMIC_SLEEP.

Scope the guard to the collection walk. The teardown does not need RCU: it
serialises on priv->rx_reorder_tbl_lock[] and frees with kfree_rcu().
