[PATCH 2/5] scripts: kwboot: allow piping full buffer size at once

[Ahmad Fatoum]

While buf == _buf, their type and sizeof differ. The read syscall should
have the buffer size as argument, but instead got the pointer's size.

This likely doesn't change high-level behavior, because read was called
in a loop, so fix this.
