Horatiu Vultur 99343cfa4f net: lan966x: Fix usage of lan966x->mac_lock when entry is removed 
To remove an entry to the MAC table, it is required first to setup the
entry and then issue a command for the MAC to forget the entry.
So if it happens for two threads to remove simultaneously an entry
in MAC table then it would be a race condition.
Fix this by using lan966x->mac_lock to protect the HW access.
