gdb: pass struct smaps_data to linux_dump_mapping_p_ftype

Simplify the argument passing in linux_find_memory_regions_full when
calling the should_dump_mapping_p callback.  Instead of pulling all
the components from the smaps_data object and passing them separately,
just pass the smaps_data object.

I think this change is justified on its own; the code seems cleaner,
and easier to read to my eye.  But additionally, in a later commit in
this series I want to pass smaps_data::has_anonymous to the
should_dump_mapping_p callback, which would mean adding yet another
argument, and I think the argument list is already long enough.
Changing the function now to pass the smaps_data object means that I
will already have the ::has_anonymous field available in the later
commit.

There should be no user visible changes after this commit.
