cifs: enable extended stats by default
CONFIG_CIFS_STATS2 can be very useful since it shows
latencies by command, and allows enabling the slow response
dynamic tracepoint which can be useful to identify
performance problems.
For example:
Total time spent processing by command. Time units are jiffies (1000 per second)
SMB3 CMD Number Total Time Fastest Slowest
