Artem Bityutskiy f3dc0e3842 lib/list_sort: test: improve errors handling 
The 'lib_sort()' test does not free memory if it fails, and it makes the
kernel panic if it cannot allocate memory.  This patch fixes the problem.

This patch also changes several small things:
 o use 'list_add()' helper instead of adding manually
 o introduce temporary 'el1' variable to avoid ugly and unreadalbe
   "if" statement
 o make 'head' to be stack variable instead of 'kmalloc()'ed, which
   simplifies code a bit

Overall, this patch is of clean-up type.
