This commit adds a default condition to those case statements that do not
already have one. This is done to provide both a logical covering of all
conditions, as well as to maintain uniformity with the rest of the Unisys
driver set.

This patch addresses the problem that we were sending double responses
back to the s-Par Firmware when processing CONTROLVM Messages. Every
message responds individually and the epilog functions would send a
response as well.
Since a message could delay the response, it was decided to remove the
extra response from the epilog function.

Previously, the sysfs entry (assuming traditional sysfs mountpoint):
/sys/bus/visorbus/devices/visorbus<n>/client_bus_info
violated kernel conventions by printing more than one item. This along
with the fact that the data emitted was diagnostic data (intended to
shadow the client driver info provided via s-Par livedumps) made it a
logical candidate for debugfs. So this patch moves this sysfs entry to
debugfs as (assuming traditional debugfs mountpoint):
/sys/kernel/debug/visorbus/visorbus<n>/client_bus_info
Data for this debugfs is emitted using the preferred seq_file interface,
which allowed a vastly-simplified version of vbuschannel_print_devinfo()
to format the individual output components.
Functionality was verified as follows:
[root@sparguest visorbus]# mount | grep debug
debugfs on /sys/kernel/debug type debugfs (rw)
[root@sparguest visorbus]# pwd
/sys/kernel/debug/visorbus
[root@sparguest visorbus]# l visorbus1/

This patch makes locking in visorchannel_signalempty statically
deterministic.
As a result this patch fixes the sparse warning:
Context imbalance in 'visorchannel_signalempty' - different lock
contexts for basic block.
The logic of the locking code doesn't change but the layout of the
original code is "frowned upon"
according to mails on sparse context checking.
Refactoring removes the warning and makes the code more readable.
