nfs: fix v4.2 SEEK on files over 2 gigs
commit 306a5549355966e480e0dcacdc6b9321d153e0c0 upstream.
We're incorrectly assigning a loff_t return to an int. If SEEK_HOLE or
SEEK_DATA returns an offset over 2^31 then the application will see a
weird lseek() result (usually -EIO).
Fixes: bdcc2cd14e4e "NFSv4.2: handle NFS-specific llseek errors"
