Call synchronize_rcpu in unregister_filesystem
Quoting Nick:
"BTW there are a few issues Al pointed out. We have to synchronize RCU
after unregistering a filesystem so d_ops/i_ops doesn't go away, and
mntput can sleep so we can't do it under RCU read lock."
This patch simply calls synchronize_rcpu in unregister_filesystem to avoid
this issue
