msm_11ad: copy FW crash dump before starting SSR flow
Currently when WIGIG FW crashes and SSR is in SYSTEM mode,
SSR causes a kernel panic and its panic handler will call
msm_11ad_ssr_crash_shutdown which will copy the FW crash
dump. However this is done when kernel panic is in progress
and kernel is not fully operational, so sometimes the copy
fails and the FW crash dump will not be found in the DDR
dump from the device.
Fix this problem by copying the FW crash dump before
notifying SSR, so the crash dump will always be copied
correctly when WIGIG FW crashes.
We also keep copying in crash_shutdown so the WIGIG FW
crash dump will be available also after normal kernel
panics, though it is not always copied in this case.
