smb3: add dynamic trace point for query_info_enter/done
Adds dynamic trace points for the query_info_enter
and query_info_done (no error) case. We only had one
existing trace point related to this which was on query_info
errors. Note that these two new tracepoints are for the
non-compounded query_info paths.
Sample output (from: trace-cmd record -e smb3_query_info*)
