staging: unisys: refactor ULTRA_check_channel_client()

Rename the function ULTRA_check_channel_client() to
spar_check_channel_client(), and fix CamelCase parameter names:

pChannel => ch
expectedTypeGuid => expected_uuid
channelName => chname
expectedMinBytes => expected_min_bytes
expectedVersionId => expected_version
expectedSignature => expected_signature

Rename macros that use spar_check_channel_client:

ULTRA_CONTROLVM_CHANNEL_OK_CLIENT => SPAR_CONTROLVM_CHANNEL_OK_CLIENT
ULTRA_VHBA_CHANNEL_OK_CLIENT => SPAR_VHBA_CHANNEL_OK_CLIENT
ULTRA_VNIC_CHANNEL_OK_CLIENT => SPAR_VNIC_CHANNEL_OK_CLIENT
ULTRA_VSWITCH_CHANNEL_OK_CLIENT => SPAR_VSWITCH_CHANNEL_OK_CLIENT
ULTRA_VBUS_CHANNEL_OK_CLIENT => SPAR_VBUS_CHANNEL_OK_CLIENT
