Subject: [PATCH V2 iproute2 2/3] devlink: Left justification on FMSG output

From: Aya Levin <ayal@...lanox.com>

FMSG output is dynamic, space separator must be on the left hand side of
the value. Otherwise output has redundant left indentation regardless
the hierarchy.

Before the patch:
 Common config: SQ: stride size: 64 size: 1024
 CQ: stride size: 64 size: 1024
 SQs:
   channel ix: 0 tc: 0 txq ix: 0 sqn: 10 HW state: 1 stopped: false cc: 0 pc: 0 CQ: cqn: 6 HW status: 0
   channel ix: 1 tc: 0 txq ix: 1 sqn: 14 HW state: 1 stopped: false cc: 0 pc: 0 CQ: cqn: 10 HW status: 0
   channel ix: 2 tc: 0 txq ix: 2 sqn: 18 HW state: 1 stopped: false cc: 5 pc: 5 CQ: cqn: 14 HW status: 0
   channel ix: 3 tc: 0 txq ix: 3 sqn: 22 HW state: 1 stopped: false cc: 0 pc: 0 CQ: cqn: 18 HW status: 0

With the patch:
Common config: SQ: stride size: 64 size: 1024
CQ: stride size: 64 size: 1024
SQs:
  channel ix: 0 tc: 0 txq ix: 0 sqn: 10 HW state: 1 stopped: false cc: 0 pc: 0 CQ: cqn: 6 HW status: 0
  channel ix: 1 tc: 0 txq ix: 1 sqn: 14 HW state: 1 stopped: false cc: 0 pc: 0 CQ: cqn: 10 HW status: 0
  channel ix: 2 tc: 0 txq ix: 2 sqn: 18 HW state: 1 stopped: false cc: 5 pc: 5 CQ: cqn: 14 HW status: 0
  channel ix: 3 tc: 0 txq ix: 3 sqn: 22 HW state: 1 stopped: false cc: 0 pc: 0 CQ: cqn: 18 HW status: 0
