scsi: qla2xxx: Remove the unused 'del_list_entry' field in struct fc_port

The 'del_list_entry' field in "struct fc_port" is unused.

The field was introduced in commit 2d70c10 ("[SCSI] qla2xxx: Add LLD
target-mode infrastructure for >= 24xx series") in 2012-05 and the last
user was removed in commit 726b854 ("qla2xxx: Add framework for async
fabric discovery") in 2017-02.

Remove this unused field.
