Merge branch 'mlxsw-Minor-cleanup'

Jiri Pirko says:

====================
mlxsw: Minor cleanup

Fix small issues I noticed during the refactoring.

First patch adds file name comments in the header file to make it clear
what goes where. Second patch fixes a typo and third patch simply aligns
RIF index allocation with similar allocations in the driver.
