[PATCH 05/13] staging: unisys: visorbus: remove unused initializations

[David Kershner]

From: sameer wadgaonkar <sameer.wadgaonkar at unisys.com>

Removed initializations from visorchipset_open() and visorchipset_init(),
and moved the memset in initialize_controlvm_payload_info() down in case
of early returns from the function.
