Remove unused resource type argument from acquire and release functions in mm_radio_rm.c

Remove unused resource type argument from acquire and release functions in mm_radio_rm.c

- In the current implementation of the mm_radio_rm.c file, the RM_CATEGORY_RADIO is the only category used for radio resources.
  Therefore, the resource type argument passed to the acquire
  and release functions is redundant and can be removed without affecting the functionality of the code.
- This change simplifies the function signatures and removes unnecessary code complexity.
