smb3: add trace point for queryfs (statfs)
In debugging a recent performance problem with statfs, it would have
been helpful to be able to trace the smb3 query fs info request
more narrowly. Add a trace point "smb3_qfs_done"
Which displays:
stat-68950 [008] ..... 1472.360598: smb3_qfs_done: xid=14 sid=0xaa9765e4 tid=0x95a76f54 unc_name=\\localhost\test rc=0
