sysfs, kernfs: introduce kernfs_rename[_ns]()
Introduce kernfs rename interface, krenfs_rename[_ns]().
This is just rename of sysfs_rename(). No functional changes.
Function comment is added to kernfs_rename_ns() and @new_parent_sd is
renamed to @new_parent for consistency with other kernfs interfaces.
v2: Dummy implementation for !CONFIG_SYSFS updated to return -ENOSYS.
