[PATCH] Remove a redundant conditional definition of list_add().

[Robert P. J. Day]

Remove the conditional surrounding the definition of list_add() from
list.h since, if you define CONFIG_DEBUG_LIST, the definition you will
subsequently pick up from lib/list_debug.c will be absolutely
identical, at which point you can remove that redundant definition
from list_debug.c as well.

  compile-tested on x86 with "make defconfig", both with and without
the list debug option.
