staging: qlge: remove mpi_core_to_log which sends coredump to the kernel ring buffer

devlink health could be used to get coredump. No need to send so much
data to the kernel ring buffer.

   of questionable value. In particular, qlge_dbg.c has hundreds of lines of
   code bitrotting away in ifdef land (doesn't compile since commit
   18c49b91777c ("qlge: do vlan cleanup", v3.1-rc1), 8 years ago).
-* triggering an ethtool regdump will hexdump a 176k struct to dmesg depending
-  on some module parameters.
 * the flow control implementation in firmware is buggy (sends a flood of pause
   frames, resets the link, device and driver buffer queues become
   desynchronized), disable it by default
