NFS: Fix a regression in nfs_file_llseek()
After commit 06222e491e663dac939f04b125c9dc52126a75c4 (fs: handle SEEK_HOLE/SEEK_DATA properly in all fs's that define their own llseek) the behaviour of llseek() was changed so that it always revalidates the file size. The bug appears to be due to a logic error in the afore-mentioned commit, which always evaluates to 'true'.
