octeontx2-pf: fix bitmap leak 



The bitmap allocated with bitmap_zalloc() in otx2_probe() was not
released in otx2_remove(). Unbinding and rebinding the driver therefore
triggers a kmemleak warning:

    unreferenced object (size 8):
      backtrace:
        bitmap_zalloc
        otx2_probe

Call bitmap_free() in the remove path to fix the leak.
