perf/ioc: Fix race causing crash when accessing freed page
ioc_inode_wakeup does not lock the ioc_inode for the duration
of the operation, leaving a window where ioc_prune could find
a NULL waitq and hence free the page which ioc_inode_wakeup later
tries to access.
Thanks to Mohit for the analysis.
