fs/pipe: fix pipe buffer index use in FUSE
This was another case that Rasmus pointed out where the direct access to
the pipe head and tail pointers broke on 32-bit configurations due to
the type changes.
As with the pipe FIONREAD case, fix it by using the appropriate helper
functions that deal with the right pipe index sizing.
