target/riscv/kvm: minor fixes/tweaks

Browse Source 
Remove an unused 'KVMScratchCPU' pointer argument in
kvm_riscv_check_sbi_dbcn_support().

Put kvm_riscv_reset_regs_csr() after kvm_riscv_put_regs_csr(). This will
make a future patch diff easier to read, when changes in
kvm_riscv_reset_regs_csr() and kvm_riscv_get_regs_csr() will be made.

Fixes: a6b53378f5 ("target/riscv/kvm: implement SBI debug console (DBCN) calls")
