[PATCH] NFS: fix fsync return code

[Takashi Iwai]

With the commit af7fa16506bf9b6323e862a61e14c20555152bb3
    NFS: Fix up the fsync code
fsync returns a postive number for success incorrectly because now it
calls nfs_commit_inode() which returns the number of pages.

This patch makes fsync simply ignore a positive return value.
