Sergey Bashirov f677cd7731 NFSD/blocklayout: Fix minlength check in proc_layoutget 
[ Upstream commit 3524b021b0 ]

The extent returned by the file system may have a smaller offset than
the segment offset requested by the client. In this case, the minimum
segment length must be checked against the requested range. Otherwise,
the client may not be able to continue the read/write operation.

Fixes: 8650b8a058 ("nfsd: pNFS block layout driver")
