ntfs: fix hole runlist memory leak in insert range error path

Browse Source 
ntfs_non_resident_attr_insert_range() allocates hole_rl before mapping the
whole runlist. If ntfs_attr_map_whole_runlist() fails, the error path drops
ni->runlist.lock and returns without freeing hole_rl. This leaks memory
of sizeof(*hole_rl) * 2 bytes.

Fix this memory leak by freeing hole_rl before returning from
that error path, matching the later error paths in the same function.
