mlxsw: core: Increase scope of RCU read-side critical section
[ Upstream commit 7d8e8f34 ] The lifetime of the Rx listener item ('rxl_item') is managed using RCU, but is dereferenced outside of RCU read-side critical section, which can lead to a use-after-free. Fix this by increasing the scope of the RCU read-side critical section.
