wifi: ath12k: Add missing qmi_txn_cancel() calls
[ Upstream commit 2e82b5f09a97f1b98b885470c81c1248bec103af ]
Per the QMI documentation "A client calling qmi_txn_init() must call
either qmi_txn_wait() or qmi_txn_cancel() to free up the allocated
resources."
Unfortunately, in most of the ath12k messaging functions, when
qmi_send_request() fails, the function returns without performing the
necessary cleanup. So update those functions to call qmi_txn_cancel()
when qmi_send_request() fails.
No functional changes, compile tested only.
