netxen: fix tx timeout recovery
Redesign tx timeout handling in line with new firmware
reset design that co-ordinates with other PCI function
drivers.
o For NX3031, first try to reset PCI function's own
context before requesting firmware reset.
o For NX2031, since firmware heartbit is not supported
directly request firmware reset.
