Kinglong Mee c929ea0b91 SUNRPC: cleanup ida information when removing sunrpc module
After removing sunrpc module, I get many kmemleak information as,
unreferenced object 0xffff88003316b1e0 (size 544):
  comm "gssproxy", pid 2148, jiffies 4294794465 (age 4200.081s)
  hex dump (first 32 bytes):

I found, the ida information (dynamic memory) isn't cleanup.
