fscache: clean up for fscache_clear_volume_priv 

hulk inclusion
category: cleanup
bugzilla: https://gitee.com/openeuler/kernel/issues/IB5UKT



--------------------------------

In the previous patch, we introduced mutex_lock to prevent concurrency
between cachefiles_free_volume() and cachefiles_withdraw_volume().

Now in fscache_clear_volume_priv(), there is no need to increase
fscache_volume->n_accesses to prevent concurrency. Remove the related code.
