AArch32: Correct sdot RTL on aarch32
The RTL Generated from <sup>dot_prod<vsi2qi> is invalid as operand3 cannot be
written to, it's a normal input. For the expand it's just another operand
but the caller does not expect it to be written to.
gcc/ChangeLog:
* config/arm/neon.md (<sup>dot_prod<vsi2qi>): Drop statements.
