[ARM] 3789/4: Fix VFP emulation to ignore VECITR for scalar instruction

VECITR in Floating-Point Exception register indicates the number of
remaining short vector iterations after a potential exception was
detected.

In case of exception caused by scalar instructions, VECITR is NOT updated.
Therefore emulation for VFP must ignore VECITR field
and treat "veclen" as zero when recognizing scalar instructing.
