Subject: fscache: fix build on !CONFIG_SYSCTL
X-Git-Tag: firefly_0821_release~9833^2~1241^2~2

fscache: fix build on !CONFIG_SYSCTL

Commit 8b8edefa (fscache: convert object to use workqueue instead of
slow-work) made fscache_exit() call unregister_sysctl_table()
unconditionally breaking build when sysctl is disabled.  Fix it by
putting it inside CONFIG_SYSCTL.
