NFS: Fix a hang/infinite loop in nfs_wb_page()
commit b8413f98f997bb3ed7327e6d7117e7e91ce010c3 upstream.
When one of the two waits in nfs_commit_inode() is interrupted, it
returns a non-negative value, which causes nfs_wb_page() to think
that the operation was successful causing it to busy-loop rather
than exiting.
It also causes nfs_file_fsync() to incorrectly report the file as
being successfully committed to disk.
This patch fixes both problems by ensuring that we return an error
if the attempts to wait fail.
