scsi: qla2xxx: Remove unused 'ql_dm_tgt_ex_pct' parameter

The ql_dm_tgt_ex_pct parameter was introduced in commit ead0385
("qla2xxx: Add Dual mode support in the driver"). Then the use of this
parameter was dropped in commit 99e1b68 ("scsi: qla2xxx: Add
ql2xiniexchg parameter").

Thus, remove ql_dm_tgt_ex_pct since it is no longer used.
