[patch] ALSA: hda/ca0132 - fix error handling for dsp_chip_to_dsp_addx()

[Dan Carpenter <dan.carpenter@oracle.com>]

The error handling here won't work on 64 bit systems.
INVALID_CHIP_ADDRESS is an unsigned long defined like this:

#define INVALID_CHIP_ADDRESS        (~0UL)

But we truncate the high bits away before returning and then we save it
in an unsigned 32bit and then we compare it against the unsigned long
version.

I've changed everything to unsigned long.
