[AArch64] More aarch64_endian_lane_rtx

r254466 failed to update some uses of ENDIAN_LANE_N that were added after
the patch was initially written, which meant that we were treating the
mode number as an element count.

gcc/
	* config/aarch64/aarch64-simd.md (aarch64_store_lane0<mode>):
	Upddate call to ENDIAN_LANE_N.
	(aarch64_<sur>dot_lane<vsi2qi>): Use aarch64_endian_lane_rtx.
	(aarch64_<sur>dot_laneq<vsi2qi>): Likewise.
	(*aarch64_simd_vec_copy_lane<mode>): Update calls to ENDIAN_LANE_N
	and use aarch64_endian_lane_rtx.
	(*aarch64_simd_vec_copy_lane_<vswap_width_name><mode>): Likewise.
