gdb.trace: Deduplicate write_inferior_data_ptr.
This function is now basically identical to write_inferior_data_pointer, remove it and change all references. gdb/gdbserver/ChangeLog: * tracepoint.c (x_tracepoint_action_download): Change write_inferior_data_ptr to write_inferior_data_pointer. (cmd_qtstart): Likewise. (write_inferior_data_ptr): Remove. (download_agent_expr): Change write_inferior_data_ptr to write_inferior_data_pointer. (download_tracepoint_1): Likewise. (download_tracepoint): Likewise. (download_trace_state_variables): Likewise.
