[PATCH v4 1/3] chrt: Make minor cleanups in chrt

[Madadi Vineeth Reddy <vineethr@linux.ibm.com>]

Minor changes such as fixing an incorrect comment and aligning
the closing brace of an if condition in main() were made, along
with making the usage of --pid consistent across files instead
of -p, although -p still works, for better readability.

No functional change is intended.
