staging: unisys: refactor init_vbus_channel()

Clean up the function definition so it's a single line. Remove the unnecessary
goto statements and just return directly. Remove the unneeded local variable
for the return result. Fix CamelCase parameters and local variable names:

channelAddr => ch_addr
channelBytes => ch_bytes
pChan => ch
