[PATCH 3/3] net-sysfs: Fix error path for kobject_init_and_add()

["Tobin C. Harding" <tobin@kernel.org>]

Currently error return from kobject_init_and_add() is not followed by a
call to kobject_put().  This means there is a memory leak.

Add call to kobject_put() in error path of kobject_init_and_add().
