[SCSI] qla1280: fix 32 bit segment code

There's an error remaining in the 32 bit descriptor code after the
conversion to dma accessors:  req_cnt is left uninitialised.

qla1280_32bit_start_scsi gives the following warnings:

drivers/scsi/qla1280.c: In function 'qla1280_32bit_start_scsi':
drivers/scsi/qla1280.c:3044: warning: unused variable 'dma_handle'
drivers/scsi/qla1280.c: In function 'qla1280_queuecommand':
drivers/scsi/qla1280.c:3060: warning: 'req_cnt' is used uninitialized in this function
drivers/scsi/qla1280.c:3042: note: 'req_cnt' was declared here
