[ Upstream commit 09f16f7390f302937409738d6cb6ce99b265f455 ]
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
