lavu/riscv: remove bogus B extension
The B Bit manipulation extension was not defined to this day, and probably never will. Instead it was broken down into Zba, Zbb, Zbc and Zbs with no particular blessed set to make up B. This removes the bogus field test. Linux never set this bit, nor (AFAICT) did FreeBSD or any other OS. We can always add it back in the unlikely event that it gets taken into use.
