net: mana: Fix memory leak in mana_gd_setup_irqs
[ Upstream commit bb1e3eb57d2cc38951f9a9f1b8c298ced175798f ]
Commit 8afefc361209 ("net: mana: Assigning IRQ affinity on HT cores")
added memory allocation in mana_gd_setup_irqs of 'irqs' but the code
doesn't free this temporary array in the success path.
This was caught by kmemleak.
