cleanup: scope reduction

[app/channel.cpp:102]:   (style) The scope of the variable 'resp' can be reduced.
[ipmisensor.cpp:310]:    (style) The scope of the variable 'i' can be reduced.
[ipmid.cpp:506]:         (style) The scope of the variable 'num_handlers' can be reduced.
[read_fru_data.cpp:82]:  (style) The scope of the variable 'fruId' can be reduced.
[sensorhandler.cpp:256]: (style) The scope of the variable 'p' can be reduced.
[storageaddsel.cpp:68]:  (style) The scope of the variable 'p' can be reduced.

Also delete two extra vertical lines.
