Commit 7fd89545 ("i40e: remove BUG_ON from feature string building")
added defective output when I40E_FLAG_VEB_MODE_ENABLED was set in
function i40e_print_features.

Fix it.

Miscellanea:

- Remove unnecessary string variable
- Add space before not after fixed strings
- Use kmalloc not kzalloc
- Don't initialize i to 0, use result of first snprintf

This change makes it so that we allow the PF to make use of all free RAR
entries for FDB use if needed.

Previously the code limited us to 16 unicast entries, however this was
shared between MACVLAN which wasn't limited and the FDB code which was.  So
instead of treating the FDB code as a second class citizen I have updated
it so that it has access to just as many entries as the MACVLAN filters.

This change replaces the ixgbe_write_uc_addr_list call in ixgbe_set_rx_mode
with a call to __dev_uc_sync instead.  This works much better with the MAC
addr list code that was already in place and solves an issue in which you
couldn't remove an FDB address without having to reset the port.

In the process of tracking down a memory leak when adding/removing FDB
entries I had to go through the MAC address configuration code for ixgbe.
In the process of doing so I found a number of issues that impacted
readability and performance.  This change updates the code in general to
clean it up so it becomes clear what each step is doing.  From what I can
tell there a couple of bugs cleaned up in this code.

First is the fact that the MAC addresses were being double counted for the
PF.  As a result once entries up to 63 had been used you could no longer
add additional filters.

A simple test case for this:
  for i in `seq 0 96`
  do
    ip link add link ens8 name mv$i type macvlan
    ip link set dev mv$i up
  done

Test script:
  ethregs -s 0:8.0 | grep -e "RAH" | grep 8000....$

When things are working correctly RAL/H registers 1 - 97 will be consumed.
In the failing case it will stop at 63 and prevent any further filters from
being added.
