====================
mlx4 fixes for 4.20-rc

First patch by Jack zeros a field in a FW communication
command, to match the FW spec.
Please queue it to -stable >= v3.17.

In the second patch I zero-initialize a variable to silence
a compliation warning.
Please queue it to -stable >= v3.19.

Third patch by Aya replaces int fields with unsigned int,
to fix a UBSAN warning.
