One aspect of the power-up functionality is the handling of the ATH11K_QMI_EVENT_FW_INIT_DONE event. When this event is received, a call is made to ath11k_hal_dump_srng_stats(), with the purpose to collect information that may be useful in debugging the cause of a firmware reset. Unfortunately, since this functionality is shared between both the firmware reset path and the power management resume path, the kernel log is flooded with messages during resume. Since these messages are not useful during resume, and in fact can be confusing and can increase the time it takes to resume, update the logic to only call ath11k_hal_dump_srng_stats() during firmware reset.
