target/riscv: Use xl instead of mxl for disassemble

Browse Source 
Disassemble function(plugin_disas, target_disas, monitor_disas) will
always call set_disas_info before disassembling instructions.

plugin_disas  and target_disas will always be called under a TB, which
has the same XLEN.

We can't ensure that monitor_disas will always be called under a TB,
but current XLEN will still be a better choice, thus we can ensure at
least the disassemble of the nearest one TB is right.
