PM: wakeup: Delete space in the end of string shown by pm_show_wakelocks()

Browse Source 
[ Upstream commit f0050a3e21 ]

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 that was added back by mistake by commit
c9d967b2ce ("PM: wakeup: simplify the output logic of
pm_show_wakelocks()").

Remove the unwanted space.

Fixes: c9d967b2ce ("PM: wakeup: simplify the output logic of pm_show_wakelocks()")
