- Remove some dead definitions, function declarations and unused
variables
- Remove an obsolete workaround from ecore_int_igu_enable()
- Remove set variables that are not used
- Remove needless check in ecore_init_wfq_param() when configuring
minimum vport BW. We already check whether total for all vports is
greater than the PF's, so no need to check independently the current
requested configuration as well.
