[PATCH 4/5] opcodes/riscv-dis.c: Make XLEN variable static

[Tsukasa OI <research_trasio@irq.a4lg.com>]

Before changing the core disassembler, we take care of minor code clarity
issues and improve readability.

Since xlen variable is not (and should not) used outside riscv-dis.c,
this commit makes this variable static.

opcodes/ChangeLog:

	* riscv-dis.c (xlen): Make this variable static.
