[PATCH 1/2] fs: sync_filesystem() not depend on BLOCK

[PATCH 1/2] fs: sync_filesystem() not depend on BLOCK

[Alexander Beregalov]

Fix this build error when CONFIG_BLOCK is not set:
fs/super.c: In function 'generic_shutdown_super':
fs/super.c:278: error: implicit declaration of function 'sync_filesystem'

sync_filesystem() is always built with or without BLOCK.
