scsi: qla2xxx: Correct endianness for rqstlen and rsplen

rqstlen and rsplen were changed to __le32 to fix sparse warnings:

drivers/scsi/qla2xxx/qla_nvme.c:402:30: warning: incorrect type in assignment (different base types)
drivers/scsi/qla2xxx/qla_nvme.c:402:30:    expected restricted __le32 [usertype] cmd_len
drivers/scsi/qla2xxx/qla_nvme.c:402:30:    got unsigned short [usertype] rsplen
drivers/scsi/qla2xxx/qla_nvme.c:507:30: warning: incorrect type in assignment (different base types)
drivers/scsi/qla2xxx/qla_nvme.c:507:30:    expected restricted __le32 [usertype] cmd_len
drivers/scsi/qla2xxx/qla_nvme.c:507:30:    got unsigned int [usertype] rqstlen
drivers/scsi/qla2xxx/qla_nvme.c:508:30: warning: incorrect type in assignment (different base types)
drivers/scsi/qla2xxx/qla_nvme.c:508:30:    expected restricted __le32 [usertype] rsp_len
drivers/scsi/qla2xxx/qla_nvme.c:508:30:    got unsigned int [usertype] rsplen

Correct the endianness in qla2xxx driver thus avoiding changes in
nvme-fc-driver.h.
