Remove three functions that are no longer used. rxrpc_get_txbuf() last use was removed by 2020's commit5e6ef4f101("rxrpc: Make the I/O thread take over the call and local processor work") rxrpc_kernel_get_epoch() last use was removed by 2020's commit44746355cc("afs: Don't get epoch from a server because it may be ambiguous") rxrpc_kernel_set_max_life() last use was removed by 2023's commitdb099c625b("rxrpc: Fix timeout of a call that hasn't yet been granted a channel") Both of the rxrpc_kernel_* functions were documented. Remove that documentation as well as the code.
