ocfs2: remove redundant l_next_free_rec check in __ocfs2_find_path()

The l_next_free_rec > l_count check after ocfs2_read_extent_block() in
__ocfs2_find_path() is now redundant, as ocfs2_validate_extent_block()
already performs this validation at block read time.

Remove the duplicate check to avoid maintaining the same validation in two
places.
