cifs: Use ULL suffix for 64-bit constant

[ Upstream commit 3995bbf53bd2047f2720c6fdd4bf38f6d942a0c0 ]

On 32-bit (e.g. with m68k-linux-gnu-gcc-4.1):

    fs/cifs/inode.c: In function ‘simple_hashstr’:
    fs/cifs/inode.c:713: warning: integer constant is too large for ‘long’ type

Fixes: 7ea884c77e5c97f1 ("smb3: Fix root directory when server returns inode number of zero")
