Subject: ext4: remove never taken branch from ext4_ext_shift_path_extents()

ext4: remove never taken branch from ext4_ext_shift_path_extents()

path[depth].p_hdr can never be NULL for a path passed to us (and even if
it could, EXT_LAST_EXTENT() would make something != NULL from it). So
just remove the branch.
