Fix checkpatch detected code style errors/warnings detected in
the file net/core/pktgen.c (remaining checkpatch checks will be addressed
in a follow up patch set).

Changes v1 -> v2:
  - drop already applied patches
  - update "net: pktgen: fix code style (ERROR: else should follow close brace
    '}')"
    Additional add braces around the else statement (as suggested by a follow
    up checkpatch run and by Jakub Kicinski from code review).
  - update "net: pktgen: fix code style (WARNING: please, no space before tabs)"
    Change from spaces to tab for indent (suggested by Jakub Kicinski).
  - update "net: pktgen: fix code style (WARNING: Prefer strscpy over strcpy)"
    Squash memset/strscpy pattern into single strscpy_pad call (suggested
    by Jakub Kicinski).
  - drop "net: pktgen: fix code style (WARNING: braces {} are not necessary for
    single statement blocks)" (suggestd by Jakub Kicinski)

Peter Seiderer (3):
  net: pktgen: fix code style (ERROR: else should follow close brace
    '}')
  net: pktgen: fix code style (WARNING: please, no space before tabs)
  net: pktgen: fix code style (WARNING: Prefer strscpy over strcpy)
