net: mana: Fix memory leak in mana_gd_setup_irqs

BugLink: https://bugs.launchpad.net/bugs/2097332

[ Upstream commit bb1e3eb ]

Commit 8afefc3 ("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.
