Cygwin: dsp: Fix SNDCTL_DSP_GET[IO]SPACE before read()/write(). 

Even with the commit 3a4c740f59, SNDCTL_DSP_GET[IO]SPACE ioctl()
does not return the fragment set by SNDCTL_DSP_SETFRAGMENT if it
is issued before read()/write(). This patch fixes the issue.

Fixes: 3a4c740f59 ("Cygwin: dsp: Implement SNDCTL_DSP_SETFRAGMENT ioctl().")
