It's supposed that odp_pmr_terms_avail() returns common number of
terms available. But some platform, like keystone, have different
number of term entries on different layers, and there is no ability
to return correct number. So, in order to be able to figure out exact
number of exact PMR terms that available, add argument - PMR term
for what the available number is requested.

But, not depending on this change, it's also impossible to know exact
number of PMR terms available in case if some PMR, depending on a
connection circumstances, can allocate two PMR terms for emulation,
actually it will be one PMR, but emulated by two. And implementation
cannot know a priori in what circumstances this entry will be used.
So, question is open....But, at least, this change allows to return
more accurate number.
