winealsa.drv: drop redundant calls

[Rafał Mużyło]

A bit of git history first:
content of dscapture.c and dsoutput.c was once a part of audio.c,
before it was split into waveout and directsound parts;
waveout was incorrectly calling and using return value of snd_pcm_delay
for awhile then, till the calls were corrected to snd_pcm_avail_update;
neither dsoutput.c nor dscapture.c are actually using the return values
and AFAICT the only purpose of snd_pcm_hwsync calls would be ensuring
that those return values are valid;

As such, those calls are most likely redundant.
