Fully fixing this would require some quite heavy refactoring to change

workqueue is empty before proceeding with the various cleanup calls,
including hci_conn_hash_flush().

ath10k: handle ieee80211 header and payload tracing separately
For packet log, the transmitted frame 802.11 header alone is sufficient.
Recording entire packet is also consuming lot of disk space. To optimize
this, tx and rx data tracepoints are splitted into header and payload
tracepoints.
To record tx ieee80211 headers
trace-cmd record -e ath10k_tx_hdr
To record complete packets
trace-cmd record -e ath10k_tx_hdr -e ath10k_tx_payload
