ath11k: Fix mon status ring rx tlv processing

Browse Source 
In HE monitor capture, HAL_TLV_STATUS_PPDU_DONE is received
on processing multiple skb. Do not clear the ppdu_info
till the HAL_TLV_STATUS_PPDU_DONE is received.

This fixes below warning and packet drops in monitor mode.
 "Rate marked as an HE rate but data is invalid: MCS: 6, NSS: 0"
 WARNING: at
 PC is at ieee80211_rx_napi+0x624/0x840 [mac80211]

Tested-on: IPQ8074 hw2.0 AHB WLAN.HK.2.4.0.1-01693-QCAHKSWPL_SILICONZ-1
