Log:
MFC nfs_bio.c 1.81, nfs_subs.c 1.86, nfs_vnops.c 1.148. Fixed two
rare-occuring bugs in NFS. First, B_CLUSTEROK must be cleared when
B_NEEDCOMMIT is cleared since uncommitted dirty buffers may not be
clustered. Second, B_NEEDCOMMIT cannot be gratuitously set in
nfs_flush(). Due to lack of locking a buffer may be added to the
dirtyblkhd list during the flush and setting B_NEEDCOMMIT can result
in the buffer's data being thrown away rather then written to the server.
