qedf: fix wrong le16 conversion
gcc points out that we are converting a 16-bit integer into a 32-bit
little-endian type and assigning that to 16-bit little-endian
will end up with a zero:
drivers/scsi/qedf/drv_fcoe_fw_funcs.c: In function 'init_initiator_rw_fcoe_task':
include/uapi/linux/byteorder/big_endian.h:32:26: error: large integer implicitly truncated to unsigned type [-Werror=overflow]
t_st_ctx->read_write.rx_id = cpu_to_le32(FCOE_RX_ID);
The correct solution appears to be to just use a 16-bit byte swap instead.
Fixes: be086e7c53f1 ("qed*: Utilize Firmware 8.15.3.0")
