Bug#46923: select count(*) from partitioned table fails with

ONLY_FULL_GROUP_BY

Problem was that during checking and preparation of the
partitioining function as a side effect in fix_fields
the full_group_by_flag was changed.

Solution was to set it back to its original value after
calling fix_fields.

Updated patch, to also exclude allow_sum_func from being
affected of fix_fields, as requested by reviewer.
