[FIX] hr_holidays: fix My Time Off access in multicompany

Before this commit, trying to access "My Time Off" was
not possible if connected on a company while some leaves
were created from another company.
This commit restricts that view to the leave created from
the companies the user is logged into.

closes odoo/odoo#122039
