Steven Rostedt (VMware) 353da87921 ftrace: Fix memory leak caused by not freeing entry in unregister_ftrace_direct() 
kmemleak reported the following:

unreferenced object 0xffff90d47127a920 (size 32):
  comm "modprobe", pid 1766, jiffies 4294792031 (age 162.568s)

The entry used to save the direct descriptor needs to be freed
when unregistering.
