[PATCH net-next 1/4] pds_core: Don't assign interrupt index/bound_intr to notifyq

[Brett Creeley <brett.creeley@amd.com>]

The notifyq rides on the adminq's interrupt, so there's
no need to setup and/or access the notifyq's interrupt
index or bound_intr. The driver sets the bound_intr
using  qcq->intx = -1 for the notifyq, but luckily
nothing accesses that field for notifyq. Instead of
expecting that remains the case, just clean up
the notifyq's interrupt index and bound_intr fields.
