qcacld-3.0: Zero-initialize soc info

pld_snoc_get_soc_info() stack allocates a icnss_soc_info struct before
populating its contents via a call to icnss_get_soc_info(). However,
icnss_get_soc_info() may not populate all of the fields of the struct.
Zero-initialize the struct before passing it to icnss_get_soc_info() to
avoid using any uninitialized values.
