[PATCH net-next] ice: Remove managed memory usage in ice_get_fw_log_cfg()

[PATCH net-next] ice: Remove managed memory usage in ice_get_fw_log_cfg()

[Christophe JAILLET]

There is no need to use managed memory allocation here. The memory is
released at the end of the function.

You kzalloc()/kfree() to simplify the code.
