[PATCH] dma: Initialize uninitialized variable

[Guenter Roeck <linux@roeck-us.net>]

Uninitialized variable results in random debug output.
Fix by initializing to 0.

This commit fixes the following warning:

drivers/dma/pch_dma.c: In function pdc_desc_get:
drivers/dma/pch_dma.c:406: warning: i may be used uninitialized in this function
