[AArch64] Don't apply mode_for_int_vector to scalars
aarch64_emit_approx_sqrt handles both vectors and scalars and was using
mode_for_int_vector even for the scalar case. Although that happened
to work, it isn't how mode_for_int_vector is supposed to be used.

* config/aarch64/aarch64.c (aarch64_emit_approx_sqrt): Use
int_mode_for_mode rather than mode_for_int_vector for scalars.
