wifi: ath12k: Avoid napi_sync() before napi_enable()
In case of MHI error a reset work will be queued which will try
napi_disable() after napi_synchronize().
As the napi will be only enabled after qmi_firmware_ready event,
trying napi_synchronize() before napi_enable() will result in
indefinite sleep in case of a firmware crash in QMI init sequence.
To avoid this, introduce napi_enabled flag to check if napi is enabled
or not before calling napi_synchronize().
