Subject: [PATCH 1/2] staging: r8188eu: remove the "dump rx packet" fragments

Remove the code fragments for printing incoming packets. There's only a
hal variable HAL_DEF_DBG_DUMP_RXPKT and the bDumpRxPkt component of
struct hal_data_8188e.

The hal variable is set by a private ioctl, it's read in
validate_recv_frame but it's not used.

All of this can be removed, there's no code to dump the packets.

Signed-off-by: Martin Kaiser <martin@...ser.cx>
