ALSA: HDA: Dont check return for snd_hdac_chip_readl
The snd_hdac_chip_readl return can never be less than zeros,
so no point in checking for the return value
This fixes following static checker warnings in
snd_hdac_ext_bus_parse_capabilities
sound/hda/ext/hdac_ext_controller.c:47
snd_hdac_ext_bus_parse_capabilities()
warn: unsigned 'offset' is never less than zero.
sound/hda/ext/hdac_ext_controller.c:54
snd_hdac_ext_bus_parse_capabilities()
warn: unsigned 'cur_cap' is never less than zero.
