[ 155/171 ] bonding: remove already created master sysfs link on failure

[Steven Rostedt]

3.6.11.2 stable review patch.
If anyone has any objections, please let me know.

------------------

From: Veaceslav Falico <vfalico@xxxxxxxxxx>

[ Upstream commit 9fe16b78ee17579cb4f333534cf7043e94c67024 ]

If slave sysfs symlink failes to be created - we end up without removing
the master sysfs symlink. Remove it in case of failure.
