Candidate #1 - pl2303_write and serial_write()

This is the small patch as requested. I know that we still have
some issues in usbserial with this patch applied. This addresses the narrow
problem only.

Also, pl2303 has to use common write methods. I guarantee that customer
will step on a hang sooner or later, if they transfer large enough amount
of data through the adapter.

A fix for this problem has just been committed to the RHEL3 U7
patch pool this evening (in kernel version 2.4.21-39.EL).
