buffer: discard BH_Write_EIO along with the rest of the buffer state
discard_buffer() strips the state that describes where a buffer lives and
what has happened to it, because after an invalidate none of it applies any
more. BH_Write_EIO belongs in that set for the same reason: it describes a
write of the data that is being thrown away.
Leaving it set means a buffer_head reused for a different block starts life
carrying somebody else's write error. Like the bforget() change, this is
mostly theoretical today and becomes load bearing once the rest of the
series makes BH_Write_EIO the report of a failed metadata write.
