[PATCH] n_tty.c buglet breaks error returns

From: Jeff Dike (jdike@karaya.com)
Date: Sat Sep 21 2002 - 12:58:30 EST

The tty SIGIO fix that went into 2.4.19 breaks error returns from the
underlying driver. Currently, any errors from the driver causes write_chan
to call schedule() rather than returning the error.

This broke the UML test suite, the fix below makes it work again.
