mlxsw: spectrum_switchdev: Don't batch STP operations

Browse Source 
Simplify the code by using the common function that sets an STP state
for a Port-VLAN and remove the existing one that tries to batch it for
several VLANs.

This will help us in a follow-up patchset to introduce a unified
infrastructure for bridge ports, regardless if the bridge is VLAN-aware
or not.
