[PATCH v2] staging: rtlwifi: Remove unnecessary function

[Maya Nakamura <m.maya.nakamura@gmail.com>]

Because the odm_signal_scale_mapping function is only called to return the
second argument, remove the function and change five statements that call
it.

Signed-off-by: Maya Nakamura <m.maya.nakamura@gmail.com>

Changes since v1:
 - Remove a function's declaration, definition, and its comment.
 - Change five statements that call the function.
