smb: client: add oplock level to smb3_open_done tracepoint

Browse Source 
Add an oplock field to the smb3_open_done_class trace event to
show the granted oplock/lease level. Move the trace_smb3_open_done
call after smb2_parse_contexts() so the oplock value reflects
the parsed lease state (R/W/H flags).
