make sis_rxeof() handle that too. Previously it used to receive the
frame and reset controller.

When VLAN tagged frame is received the hardware sets 'LONG' bit of
Rx status word. It is always set when the size of received frame
exceeded 1518 bytes, including CRC. This VLAN tagged frame clears
'OK' bit of Rx status word such that driver should not rely on 'OK'
bit of Rx status word to pass the VLAN tagged frame to upper stack.
To fix the bug, don't use SIS_CMDSTS_PKT_OK for Rx error check and
introduce SIS_RXSTAT_ERROR macro that checks Rx errors. If we are
configured to accept VLAN tagged frames and the received frame size
is less than or equal to maximum allowed length of VLAN tagged
frame, clear 'LONG' bit of Rx status word before checking Rx
errors.

night.
Free the children after each pci bus that is searched. Otherwise we
leak them. With free in the new place, we also have to free children
before going to done when we find the device we're looking for.
Also, if we can't get the children of a device, just ignore that bus.

face of errors already... A bit unorthodox, but none-the-less valid.
