target/riscv: gdbstub: Fix dynamic CSR XML generation 

Since commit 605def6eee ("target/riscv: Use the RISCVException enum for CSR operations")
the CSR predicate() function was changed to return RISCV_EXCP_NONE
instead of 0 for a valid CSR, but it forgot to update the dynamic
CSR XML generation codes in gdbstub.

Fixes: 605def6eee ("target/riscv: Use the RISCVException enum for CSR operations")
