integrity: Fix possible multiple allocation in integrity_inode_get()
When integrity_inode_get() is querying and inserting the cache, there
is a conditional race in the concurrent environment.
The race condition is the result of not properly implementing
"double-checked locking". In this case, it first checks to see if the
iint cache record exists before taking the lock, but doesn't check
again after taking the integrity_iint_lock.
Fixes: bf2276d10ce5 ("ima: allocating iint improvements")
