    Impact: fix an oops which always triggers
    
    ide_tape_issue_pc() assumed drive->pc isn't NULL on invocation when
    checking for back-to-back request sense issues but drive->pc can be
    NULL and even when it's not NULL, it's not safe to dereference it once
    the previous command is complete because pc could have been freed or
    was on stack.  Kill back-to-back REQUEST_SENSE detection.
