Fix a compile warning with -DDEBUG.

An unguarded write() in the dputs function caused gcc -Werror to fail
to compile. I'm confused that this hasn't bitten me before, though -
obviously normal builds of PuTTY condition out the faulty code, but
_surely_ this can't be the first time I've enabled the developer
diagnostics since gcc started complaining about unchecked syscall
returns!
