lib/test_sort.c: add module unload support
test_sort.c performs array-based and linked list sort test. Code allows
to compile either as a loadable modules or builtin into the kernel.
Current code is not allow to unload the test_sort.ko module after
successful completion.
This patch adds support to unload the "test_sort.ko" module by adding
module_exit support.
Previous patch was implemented auto unload support by returning -EAGAIN
from module_init() function on successful case, but this approach is not
ideal.
The auto-unload might seem like a nice optimization, but it encourages
inconsistent behaviour. And behaviour that is different from all other
normal modules.
