Same location, just as previous panics.

I've put some if_printf's in the re_init function to try to narrow it
down but haven't managed to figure anything out yet.
System paniced when we wrote to RE_TXCFG, with (RE_TXCFG_IDG |
RE_TXCFG_MAXDMA).  The register and the value are both valid for
RTL8101E.  So something wrong must happened, in either:
1) re_stop()
2) IDR config
Rest of the things before setting RE_TXCFG is all valid for RTL8101E
So I commented out IDR config in re_init() and added re_reset().  IDRs
will be autoloaded, if card is initially powered on, and the value in
IDRs can survive the reset command.  So let's just see whether it
still panics:
