From: Ofer Heifetz <oferh@marvell.com>

When mixing bit-field and none bit-filed in packed struct the
none bit-field starts at a distinct memory location, thus adding
an additional byte to the overall structure which is used in
memory zero-ing and other configuration calculations.

Fix this by removing the none bit-field that has a following
bit-field.
