Subject: [PATCH AUTOSEL 5.2 201/249] ath10k: Fix memory leak in qmi

From: Dundi Raviteja <dundi@...eaurora.org>

[ Upstream commit c709df58832c5f575f0255bea4b09ad477fc62ea ]

Currently the memory allocated for qmi handle is
not being freed during de-init which leads to memory leak.

Free the allocated qmi memory in qmi deinit
to avoid memory leak.

Tested HW: WCN3990
Tested FW: WLAN.HL.3.1-01040-QCAHLSWMTPLZ-1

Fixes: fda6fee0001e ("ath10k: add QMI message handshake for wcn3990 client")
