scsi: libfc: Include the correct header

This file does not use rcu, so there is no point in including
<linux/rculist.h>.

The dependency has been removed in commit fa519f701d27 ("scsi: libfc: fixup
'sleeping function called from invalid context'") It turned a
list_for_each_entry_rcu() into a list_for_each_entry().

So just #include <linux/list.h> now.
