octeontx2-af: Fix irq free in rvu teardown

Browse Source 
[ Upstream commit ae2619dd4f ]

Current devlink code try to free already freed irqs as the
irq_allocate flag is not cleared after free leading to kernel
crash while removing rvu driver. The patch fixes the irq free
sequence and clears the irq_allocate flag on free.

Fixes: 7304ac4567 ("octeontx2-af: Add mailbox IRQ and msg handlers")
