scsi: qla2xxx: Add 29xx extended logio IOCB support

Browse source 
The 29xx series uses a wider IOCB stride (128 bytes vs 64 bytes).  The
logio_entry_24xx_ext layout extends logio_entry_24xx with a wider
vp_index field (__le16 vs u8) while keeping all other read-side fields
(comp_status, io_parameter[0..10], entry_status) at identical offsets
and widths.

Update the logio IOCB builder functions (qla24xx_login_iocb,
qla24xx_logout_iocb, qla24xx_prli_iocb, qla24xx_prlo_iocb,
qla24xx_adisc_iocb) to accept a void pointer and dispatch the vp_index
write through IS_QLA29XX(), using an inline cast to the extended layout
at the single write site.

In the completion handler qla24xx_logio_entry(), accept a void pointer
and read through a single logio_entry_24xx view since all accessed
fields sit at the same offsets in both layouts.  Use the
qla_req_entry_size() helper for the dump buffer size.

In qla24xx_login_fabric() and qla24xx_fabric_logout(), allocate through
a void pointer from the DMA pool and dispatch vp_index via the same
inline-cast pattern.

Add a BUILD_BUG_ON for logio_entry_24xx_ext to enforce the 128-byte size
invariant at compile time.
