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.
