tracing: Remove extra space at the end of hwlat_detector/mode

Browse Source 
[ Upstream commit 2cf0dee989 ]

Space is printed after each mode value including the last one:
$ echo \"$(sudo cat /sys/kernel/tracing/hwlat_detector/mode)\"
"none [round-robin] per-cpu "

Found by Linux Verification Center (linuxtesting.org) with SVACE.
