CE buffers are cleaned up prior to napi disable and this is causing
NULL pointer dereference due to "use after free".
Disable napi before resource cleanup to avoid "use after free".

There is unbalanced napi_{enable,disable}() behavior as they
are being called from hif_snoc_{power_up/stop).
The fix is to call napi_enable() from ath10k_snoc_hif_start()
so that it matches with napi_disable() being called from
ath10k_snoc_hif_stop().

My wifi connection suddently crashed and refused reassociate after waking up
from sleep and being ilde for some time. I rebooted the machine and everything
went back to normal. This is the first time I've seen this.
I managed to get a dmesg before reboot, which should be attached in this email.
