RDMA/bnxt_re: Remove the sriov config callback
Remove the SRIOV config callback which the bnxt_en was calling
to reconfigure the chip resources for a PF device when VFs are
created. The code is now modified to provision the VF resources
based on the total VF count instead of the actual VF count.
This allows the SRIOV config callback to be removed from the
list of ulp_ops.
