[PATCH 5.15 111/121] hwmon: (mr75203) update pvt->v_num and vm_num to the actual number of used sensors

[ Upstream commit bb9195bd6664d94d71647631593e09f705ff5edd ]

This issue is relevant when "intel,vm-map" is set in device-tree, and
defines a lower number of VMs than actually supported.

This change is needed for all places that use pvt->v_num or vm_num
later on in the code.
