MFC r366929 and r367608.

r366929:
cxgbe(4): fix the size of the iq/eq maps.

The firmware can allocate ingress and egress context ids anywhere from
its configured range.  Size the iq/eq maps to match the entire range
instead of assuming that the firmware always allocates the first
available context id.

r367608:
cxgbev(4): Make sure that the iq/eq map sizes are correct for VFs.

This should have been part of r366929.
