s390/uapi: correct whitespace & coding style in asm/ptrace.h

hbrueckner · borkmann · commit 62e1dfa3e1e3 · 2017-12-05T15:02:41.000+01:00
Correct whitespace and coding style issues in the s390 asm/ptrace.h
uapi header file.  This is preparatory work to copy it to the tools/
directory for inclusion by selftests and perf.
