scsi: qla2xxx: Update handling of ELS IOCBs for 29xx series

Browse source 
Update ELS IOCB handling to support the extended 128-byte
els_entry_24xx_ext structure used by 29xx series adapters.

Change the signatures of qla24xx_els_logo_iocb(), qla_els_pt_iocb(), and
qla24xx_els_iocb() to accept a generic void pointer, enabling
differentiation between standard and extended ELS structures at runtime.

Introduce a static inline helper qla_els_set_vp_sof() in qla_inline.h
that centralises the 24xx-vs-29xx vp_index/sof_type encoding: the 24xx
layout uses separate u8 vp_index + u8 sof_type (EST_SOFI3), while 29xx
uses a __le16 with bitfields (vp_index:9 / sof_type:4 /
ELS_EXT_EST_SOFI3).  All ELS issue paths now call this helper instead of
open-coding the branch, including the RDP response path in qla_os.c.

In qla2x00_start_sp(), collapse the IS_QLA29XX() branch for the handle
assignment in SRB_ELS_CMD_HST_NOLOGIN: els_entry_24xx::handle and
els_entry_24xx_ext::handle are both u32 at offset 4, so a single
24xx-view write is layout-compatible with both strides.

DMA allocations in qla24xx_process_abts() and
qla24xx_process_purex_rdp() are updated to use the correct size for the
adapter type.  A BUILD_BUG_ON is added to verify the extended structure
size.
