target-arm/translate-a64.c: Fix dead ?: in handle_simd_shift_fpint_co…

…nv()

In handle_simd_shift_fpint_conv(), the combination of is_double == true,
is_scalar == false and is_q == false is an unallocated encoding; the
'both parts false' case of the nested ?: expression for calculating
maxpass is therefore unreachable and can be removed.
