btrfs: simplify parameters of backref iterators

The inode reference iterator interface takes parameters that are derived
from the context parameter, but as it's a void* type the values are
passed individually.

Change the ctx type to inode_fs_path as it's the only thing we pass and
drop any parameters that are derived from that.
