net/qede/base: fix numbering L2 VF queues

There are some constellations where Due to lack of resource allocation
in MFW, There would be an insufficient number of L2 queues for all the
VFs.

This introduces a new feature ECORE_VF_L2_QUE which correctly numbers
the number of VF queues. Notice it might be larger than the actual
number of VFs in configuration space, in which case its the ecore
client responsibility not to try activating that many.

As part of the fix, also correct the nubmering of the VF queues. As
their numbering is dependent on the SBs of the PF, which might only be
partially used by L2 [as half would be assigned for RDMA which doesn't
require L2 queues], we make the numbering consecutive with that of the
L2 queues only.
