Data pages in gcdat metadata file (i.e. the secondary DAT for GC), are cleared or even moved back to the normal DAT when a shot of garbage collection was done. Buffer heads held by the palloc cache of gcdat must be cleared before these page cache manipulation. This adds nilfs_palloc_clear_cache() to ensure this.
