Takashi Yano 37ab3e0d55 Cygwin: pipe: Fix a regression that raw_write() slows down ...

After the commit 7f3c22532577, writing to pipe extremely slows down.
This is because cygwait(select_sem, 10, cw_cancel) is called even
when write operation is already completed. With this patch, the
cygwait() is called only if the write operation is not completed.

Fixes: 7f3c22532577 ("Cygwin: pipe: handle signals explicitely in raw_write")
