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.
