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

[Geert Uytterhoeven]

On 32-bit:

    fs/nfsd/blocklayout.c: In function ânfsd4_block_get_device_info_scsiâ:
    fs/nfsd/blocklayout.c:337: warning: integer constant is too large for âlongâ type
    fs/nfsd/blocklayout.c:344: warning: integer constant is too large for âlongâ type
    fs/nfsd/blocklayout.c: In function ânfsd4_scsi_fence_clientâ:
    fs/nfsd/blocklayout.c:385: warning: integer constant is too large for âlongâ type

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