Xiaotian Feng 8007f10259 selinux: fix memory leak in sel_make_bools
In sel_make_bools, kernel allocates memory for bool_pending_names[i]
with security_get_bools. So if we just free bool_pending_names, those
memories for bool_pending_names[i] will be leaked.

This patch resolves dozens of following kmemleak report after resuming
from suspend:
unreferenced object 0xffff88022e4c7380 (size 32):
  comm "init", pid 1, jiffies 4294677173
