Qingfang Deng 442312c2a9 net: stmmac: Fix accessing freed irq affinity_hint
[ Upstream commit c60d101a226f18e9a8f01bb4c6ca2b47dfcb15ef ]

The cpumask should not be a local variable, since its pointer is saved
to irq_desc and may be accessed from procfs.
To fix it, use the persistent mask cpumask_of(cpu#).
