BUG/MEDIUM: tasks: fix possible segfault on task_destroy()

Commit 3f795f7 ("MEDIUM: tasks: Merge task_delete() and task_free() into
task_destroy().") replaced task_delete() and task_free() with a single
function named task_destroy().

This patch adds a check for struct task* argument in function
task_destroy() to prevent a possible segfault on NULL and also to make
the function safer for use in other cases.
