target,flash: allow target_free_working_area on NULL area pointer

Browse Source 
Standard C library free() allows NULL pointer as a parameter.

Change target_free_working_area() to conform this convention.

Remove NULL pointer tests before target_free_working_area() calls.

While on it add missing setting pointer to NULL after target_free_working_area().
