Fix checkpatch code style warnings:

  WARNING: macros should not use a trailing semicolon
  kernel-patches#180: FILE: net/core/pktgen.c:180:
  +#define func_enter() pr_debug("entering %s\n", __func__);

  WARNING: macros should not use a trailing semicolon
  kernel-patches#234: FILE: net/core/pktgen.c:234:
  +#define   if_lock(t)           mutex_lock(&(t->if_lock));

  CHECK: Unnecessary parentheses around t->if_lock
