Subject: [PATCH] nfds: Fix NFSD_MDS_PR_KEY on 32-bit by adding ULL postfix

On 32-bit:

    fs/nfsd/blocklayout.c: In function ‘nfsd4_block_get_device_info_scsi’:
    fs/nfsd/blocklayout.c:337: warning: integer constant is too large for ‘long’ type
    fs/nfsd/blocklayout.c:344: warning: integer constant is too large for ‘long’ type
    fs/nfsd/blocklayout.c: In function ‘nfsd4_scsi_fence_client’:
    fs/nfsd/blocklayout.c:385: warning: integer constant is too large for ‘long’ type

Add the missing "ULL" postfix to 64-bit constant NFSD_MDS_PR_KEY to fix
this.

Despite Bruce's "Thanks, applying for 4.6.--b." on 2016-03-29, this
still hasn't made it into next-20160603.
