[committed] RISC-V: Fix wrong predicator for zero_extendsidi2_internal pattern

[Kito Cheng]

We're wrongly guard zero_extendsidi2_internal pattern both ZBA and ZBB,
only ZBA provide zero_extendsidi2 instruction.

gcc/ChangeLog

        * config/riscv/riscv.md (zero_extendsidi2_internal): Allow ZBB
        use this pattern.
