scsi: aic7xxx: Fix REQUEST SENSE allocation length on big-endian hosts
The REQUEST SENSE length was taken from sg->len after the AHC_DMA_LAST_SEG
flag was or-ed in and the value converted to little-endian, so the 8-bit
field is 0x80 on big-endian hosts and the target is asked for 128 bytes
into a 32-byte buffer. Use the buffer size, as aic79xx does. On an SGI O2
with a Fujitsu MAX3147NC, the sense data of its CHECK CONDITIONs during
probe was lost.
