RDMA/irdma: Fix SIGBUS in AEQ destroy

Browse Source 
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: b800e82feb ("RDMA/irdma: Add GEN3 support for AEQ and CEQ")
