Merge of r4461: upstream: fixed "too big header" check.

If header filter postponed processing of a header by returning NGX_AGAIN
and not moved u->buffer->pos, previous check incorrectly assumed there
is additional space and did another recv() with zero-size buffer.  This
resulted in "upstream prematurely closed connection" error instead
of correct "upstream sent too big header" one.

Patch by Feibo Li.
