pm_show_wakelocks() is called to generate a string when showing attributes
/sys/power/wake_(lock|unlock), but the string ends with an unwanted space
the space was added back by mistake by commit c9d967b2ce40
("PM: wakeup: simplify the output logic of pm_show_wakelocks()").

Remove the unwanted space.
