[PATCH] ntdll: Only add a module dependency if import_dll() returned a modref.

[Henri Verbeet]

In particular, if import_dll() skips an unused import, it will return TRUE,
but set *pwm to NULL. This fixes a regression in 3DMark03 version 3.4.0,
introduced by commit 0dd37b02f99f5090dd855343fcd8a99496047f3e.
