libie: depend on DEBUG_FS when building LIBIE_FWLOG
LIBIE_FWLOG is unusable without DEBUG_FS. Mark it in Kconfig. Fix build error on ixgbe when DEBUG_FS is not set. To not add another layer of #if IS_ENABLED(LIBIE_FWLOG) in ixgbe fwlog code define debugfs dentry even when DEBUG_FS isn't enabled. In this case the dummy functions of LIBIE_FWLOG will be used, so not initialized dentry isn't a problem.
