scsi: qla2xxx: Enhance task management IOCB handling for 29xx series

Browse source 
Update qla24xx_tm_iocb() and __qla24xx_issue_tmf() to support the
extended task management structure (tsk_mgmt_entry_ext) for 29xx
adapters.

tsk_mgmt_entry_ext overlays tsk_mgmt_entry through control_flags
(offsets 0-27 are byte-identical): entry_type, entry_count, handle,
nport_handle, timeout, lun and control_flags sit at the same offsets and
widths.  The layouts diverge only after that point:

  - the 24xx layout has port_id[3] + u8 vp_index;

  - the ext layout has __le16 vp_index and no port_id.

Factor the common IOCB header writes through a single tsk_mgmt_entry *
view and branch on IS_QLA29XX() only for the diverging port_id /
vp_index assignments.  Change qla24xx_tm_iocb() to accept void *pkt to
allow casting to either structure type.

Add tsk_ext member to the tsk_mgmt_cmd union and a BUILD_BUG_ON size
check for the 128-byte extended structure.
