net: netpoll: remove unused netpoll pointer from netpoll_info

The netpoll_info structure contains an useless pointer back to its
associated netpoll. This field is never used, and the assignment in
__netpoll_setup() is does not comtemplate multiple instances, as
reported by Jay[1].

Drop both the member and its initialization to simplify the structure.
