Jianmin Zhu 7630ff783b qcacmn: Fix delay when request dp stats when RTPM suspended ...

When RTPM suspended, wlan_hdd_cfg80211_stats_ext_request and
dp_peer_rxtid_stats are called to get tx rx status, dp and ring
spin_lock_bh is held, if RTPM suspended, printk happens in
hif_pm_runtime_get which consumes 1 ms. In dp_peer_rxtid_stats,
REO cmd CMD_GET_QUEUE_STATS and CMD_FLUSH_CACHE are called for each of
17 tid, so total 34 printk delayed 34 ms.

To fix it, disable prink in hif_pm_runtime_get when called in
dp_peer_rxtid_stats.
