drv_pkt_delay_max should be assigned non-zero value, so that
packet delay can be accumulate in the right way.

in certain scenarios, this patch handles these cases.

If we are not able to read registers or PCIe memory,
it means PCIe device is in bad state. We will skip
firmware dump in this case.

memory_type_mapping strucuture did not refer to other mwifiex
specific strture. A better software design method would keep
it in decl header file, which does not include other mwifiex
header file.

Current firmware dump solution support w8897 chipset, this
patch extend the exist framework with support for w8997
chipset.
Trigger firmware dump using,
cat /sys/kernel/debug/mwifiex/mlan0/device_dump,
data can be obtain by
cat /sys/class/devcoredump/devcd*/data > data.txt after that.
