coresight: cti: Fix remove sysfs link error
[ Upstream commit 1cce921 ] CTI code to remove sysfs link to other devices on shutdown, incorrectly tries to remove a single ended link when these are all double ended. This implementation leaves elements in the link info structure undefined which results in a crash in recent tests for driver module unload. This patch corrects the link removal code.
