atm: remove the unused pre_send and send_bh device operations
atmdev_ops::pre_send (a TX pre-processing hook) and ::send_bh (a
bottom-half capable send variant) have no implementation behind them:
no remaining ATM driver sets either, so vcc_sendmsg() always skipped
pre_send and the raw AAL0/AAL5 paths always fell back to ->send().
The drivers that used these hooks were removed with the legacy ATM
adapters.
Drop both operations and the dead branches that tested for them.
