Only set no_cursor_timeout when requested

Browse Source 
Previously this was always set for all requests. The parameter is only
documented as supported for certain queries, so this was probably wrong.

Mongo version 4.2 fails update queries that have this parameter set making
mongoengine unusable there. Fixes #2148.
