Subject: [RESEND PATCH 07/11] soundwire: generic_bandwidth_allocation: remove useless init

From: Pierre-Louis Bossart <pierre-louis.bossart@...ux.intel.com>

Cppcheck complains about two possible null pointer dereferences, but
it's more like there are unnecessary initializations before walking
through a list.
