riscv: Fix Zbb alternative IDs

Browse Source 
Commit 4bf8860760 ("riscv: cpufeature: extend
riscv_cpufeature_patch_func to all ISA extensions") switched ISA
extension alternatives to use the RISCV_ISA_EXT_* macros instead of
CPUFEATURE_*. This was mismerged when applied on top of the Zbb series,
so the Zbb alternatives referenced the wrong errata ID values.

Fixes: 9daca9a5b9 ("Merge patch series "riscv: improve boot time isa extensions handling"")
