fscache: Fix the volume collision wait condition
The condition that the waits in fscache_wait_on_volume_collision() are
waiting until are inverted. This suddenly started happening on the
upstream kernel with something like the following appearing in dmesg when
running xfstests:
CacheFiles: cachefiles: Inode already in use: Iafs,example.com,100055
Fix them by inverting the conditions.
Fixes: 62ab63352350 ("fscache: Implement volume registration")
