fs/block_dev: always invalidate cleancache in invalidate_bdev()

Browse source 
commit a5f6a6a9c7 upstream.

invalidate_bdev() calls cleancache_invalidate_inode() iff ->nrpages != 0
which doen't make any sense.

Make sure that invalidate_bdev() always calls cleancache_invalidate_inode()
regardless of mapping->nrpages value.

Fixes: c515e1fd36 ("mm/fs: add hooks to support cleancache")
