fix: backflush raw material based on - Material Transferred for Manufacture

Hi @nabinhait ,
 
Issue : Manufacturing setting > Backflush Raw Material Based on “Material Transferred for Manufacture” doesn't fetch the actual raw material transferred qty. It fetches qty based on "BOM"

The issue is because @creamdory in PR #frappe#13384
commit : https://github.com/frappe/erpnext/pull/13384/files#diff-91f0ed661ef4b6e1f167fc7961b1a79b

```
changed from: if trans_qty and manufacturing_qty >= (produced_qty + flt(self.fg_completed_qty)):
to : if trans_qty and manufacturing_qty > (produced_qty + flt(self.fg_completed_qty)):
```
**'='** was added by her in the condition, which was not there before her commit.
Kindly except the fix for the issue.
