[FIX] hr_holidays: fix search on leave type

**Steps to reproduce:**
Navigate to Time Off >> Configuration >> Time Off Types >> Open any type, navigate to the Smart button Time Off >> Click on New >> Time Off Type
Leads to an error.

**Reason:**
The `op` function is a comparison operator function that expects two values to compare and we are only passing to it `leave_type.virtual_remaining_leaves` parameter.

**Solution:**
Added the missing `value` parameter.
