[PATCH iwl-net v1] ixgbe: guard fwlog code by CONFIG_DEBUG_FS

[Michal Swiatkowski <michal.swiatkowski@linux.intel.com>]

Building the ixgbe without CONFIG_DEBUG_FS leads to a build error. Fix
that by guarding fwlog code.

Fixes: 641585bc978e ("ixgbe: fwlog support for e610")
Reported-by: Guenter Roeck <linux@roeck-us.net>
Closes: https://lore.kernel.org/lkml/f594c621-f9e1-49f2-af31-23fbcb176058@roeck-us.net/
