dso__load_sym_internal() passed curr_mapp as an out argument to dso__process_kernel_symbol(). The out argument was never used so remove it to simplify the reference counting logic. Simplify reference counting issues with curr_dso by ensuring the value it points to has a +1 reference count, and then putting as necessary. This avoids some reference counting games when the dso is created making the code more obviously correct with some possible introduced overhead due to the reference counting get/puts. This, however, silences reference count checking and we can always optimize from a seemingly correct point.
