octeontx2-af: Fix mbox INTR handler when num VFs > 64

Geetha sowjanya · kuba-moo · commit 0fdba88a2115 · 2025-03-31T16:52:02.000-07:00
When number of RVU VFs > 64, the vfs value passed to "rvu_queue_work" function is incorrect. Due to which mbox workqueue entries for VFs 0 to 63 never gets added to workqueue.
