wifi: ath12k: Handle PPDU spread across multiple buffers
Each PPDU contains numerous TLV tags. HAL_RX_PPDU_START marks the start
of the PPDU, and HAL_RX_PPDU_END_STATUS_DONE marks the end. From the
monitor destination rings, the driver retrieves skb containing these
TLV tags and their corresponding data. Sometimes, one PPDU’s information
spreads across multiple skbs. The current parsing logic uses memset on
struct hal_rx_mon_ppdu_info after parsing each skb, leading to information
loss if a PPDU spans multiple skbs. Fix this by setting the
ppdu_continuation flag when the driver fails to get
HAL_RX_PPDU_END_STATUS_DONE, and do memset on struct
hal_rx_mon_ppdu_info only when the ppdu_continuation flag is not set.
