mlxsw: Use refcount_t for reference counting

Browse source

[ Upstream commit 1267f7223b ]

mlxsw driver uses 'unsigned int' for reference counters in several
structures. Instead, use refcount_t type which allows us to catch overflow
and underflow issues. Change the type of the counters and use the
appropriate API.
