xfs: fix type mismatches in the inode reclaim functions

It's currently unlikely that we will ever end up with more than 4
billion inodes waiting for reclamation, but the fs object code uses long
int for object counts and we're certainly capable of generating that
many.  Instead of truncating the internal counters, widen them and
report the object counts correctly.
