Coverity complains that in functions like pci_set_word_by_mask()
we might end up shifting by more than 31 bits. This is true,
but only if the caller passes in a zero mask. Help Coverity out
by asserting that the mask argument is valid.

Note that only 1 of these 4 functions is used, and that only
in 2 places in the codebase. In both cases the mask argument
is a compile-time constant.
