RDMA/irdma: Fix SIGBUS in AEQ destroy

[ Upstream commit 5eff1ecce30143c3f8924d91770d81d44bd5abe5 ]

Removes write to IRDMA_PFINT_AEQCTL register prior to destroying AEQ,
as this register does not exist in GEN3+ hardware and this kind of IRQ
configuration is no longer required.

Fixes: b800e82feba7 ("RDMA/irdma: Add GEN3 support for AEQ and CEQ")
