writeback: remove .nonblocking and .encountered_congestion
Remove two unused struct writeback_control fields: .encountered_congestion (completely unused) .nonblocking (never set, checked/showed in XFS,NFS/btrfs) The .for_background check in nfs_write_inode() is also removed btw, as .for_background implies WB_SYNC_NONE.
