[ Upstream commit f8a595a87e93a33a10879f4b856be818d2f53c84 ]
When ath10k_qmi_init() fails, the error handling does not free the irq
resources, which causes an issue if we EPROBE_DEFER as we'll attempt to
(re-)register irqs which are already registered.
Fix this by doing a power off since we just powered on the hardware, and
freeing the irqs as error handling.
Fixes: ba94c753ccb4 ("ath10k: add QMI message handshake for wcn3990 client")
