net: hns3: use mutex vport_lock instead of mutex umv_lock
Currently, the driver use mutex umv_lock to protect the variable vport->share_umv_size. And there is already a mutex vport_lock being defined in the driver, which is designed to protect the resource of vport. So we can use vport_lock instead of umv_lock. Furthermore, there is a time window for protect share_umv_size between checking UMV space and doing MAC configuration in the lin function hclge_add_uc_addr_common(). It should be extended. This patch uses mutex vport_lock intead of spin lock umv_lock to protect share_umv_size, and adjusts the mutex's range.
