smb3: add missing tracepoint for querying wsl EAs

We had tracepoints for the return code for querying WSL EAs
(trace_smb3_query_wsl_ea_compound_err and
trace_smb3_query_wsl_ea_compound_done) but were missing one for
trace_smb3_query_wsl_ea_compound_enter.

Fixes: ea41367 ("smb: client: introduce SMB2_OP_QUERY_WSL_EA")
