Bug 22140: Use of EasyAnalyticalRecords pref is get_hostitemnumbers_of

Like Bug 20702 defined GetHostItemsInfo does nothing if EasyAnalyticalRecords pref is disabled, get_hostitemnumbers_of must be dependant on this pref too.

Test plan :
1) Build an analytical record with 773$0 and $9
2) Enable EasyAnalyticalRecords
4) Place an hold on the record
5) => You see the linked item
6) Disable EasyAnalyticalRecords
7) Place an hold on the record
8) => You dont see the linked item
