mshv: Use kfree_rcu in mshv_portid_free

mshv_portid_free() uses synchronize_rcu() followed by kfree() to reclaim port table entries. This blocks the caller until a full RCU grace period elapses, which is unnecessary since the same module already uses the non-blocking kfree_rcu() pattern in mshv_port_table_fini(). Replace with kfree_rcu() to avoid the blocking wait and keep the reclamation strategy consistent across the file.
