[PATCH] bpf: disasemble offsets of value 0 as "+0"

[David Faust <david.faust@oracle.com>]

This tiny patch makes the BPF disassembler to emit, e.g.

  ldxdw %r1, [%r0+0]

instead of

  ldxdw %r1, [%r00]

when the offset is 0, to avoid confusion.

Tested on bpf-unknown-none.
Maybe obvious, but.. OK?

Thanks.

	* bpf-dis.c (print_insn_bpf): Print 16-bit offsets with value 0
	as "+0".
