ice: replace u8 elements with bool where appropriate

ice: replace u8 elements with bool where appropriate

In preparation for the new LAG functionality implementation, there are
a couple of existing LAG elements of the capabilities struct that should
be bool instead of u8.  Since we are adding a new element to this struct
that should also be a bool, fix the existing LAG u8 in this patch and
eliminate !! operators where possible.
