hwmon: (w83795) Merge w83795_create_files and w83795_remove_files 

Functions w83795_create_files and w83795_remove_files iterate over
the same set of files, just calling a different function. Merge them
into a single function which takes the action as a parameter. This
saves code, and also ensure that file creation and deletion are in
sync.
