scsi: qla2xxx: Replace __le16 bitfields with scalar and accessors

Browse source 
C bitfield packing order is implementation-defined: GCC packs LSB-first
on little-endian targets and MSB-first on big-endian targets.  The
__le16 bitfield declarations for vp_index/sof_type in the 29xx extended
IOCB structures produce incorrect bit positions on big-endian hosts, and
Sparse cannot enforce endianness checks on bitfield members.

Replace the three sets of __le16 bitfields (in els_entry_24xx_ext,
els_sts_entry_24xx_ext, and abts_entry_24xx_ext) with a single __le16
scalar field and provide inline accessor functions that use proper
le16_to_cpu()/cpu_to_le16() with shift-and-mask operations.
