staging: unisys: refactor ULTRA_check_channel_server()

Rename spar_check_channel_server() to spar_check_channel_server(),
remove unused parameters fileName, lineNumber, and logCtx, update
references to the function and remove unused parameters in macros that
call it, and fix CamelCase names:

typeGuid => typeuuid
channelName => name
expectedMinBytes => expected_min_bytes
actualBytes => actual_bytes
