fs: add missing prefetch.h include
Fixes this build error on s390 and probably other archs as well:
fs/inode.c: In function 'new_inode':
fs/inode.c:894:2: error: implicit declaration of function 'spin_lock_prefetch'
Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com>
[ Happens on architectures that don't define their own prefetch
functions in <asm/processor.h>, and instead rely on the default
ones in <linux/prefetch.h> - Linus]
