tools: iio: generic_buffer: Fix generic scale extraction
When using generic_buffer to read data, the scale is not properly detected for scale shared by type. This is caused by a problem with the generation of generic name out of the full name. E.g.: for current->name in_accel_z, the extracted generic name is "in" (when it should be "in_accel"). This is used in generic_buffer to generate scale and offset paths (in_accel_scale). Consider the in_ or out_ prefix when extracting the generic name from the full name.
