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):
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................

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