scsi: ibmvscsis: Silence -Warray-bounds warning
Instead of doing a cast to storage that is too small, add a union for the
high 64 bits. Silences the warnings under -Warray-bounds:
drivers/scsi/ibmvscsi_tgt/ibmvscsi_tgt.c: In function 'ibmvscsis_send_messages':
drivers/scsi/ibmvscsi_tgt/ibmvscsi_tgt.c:1934:44: error: array subscript 'struct viosrp_crq[0]' is partly outside array bounds of 'u64[1]' {aka 'long long unsigned int[1]'} [-Werror=array-bounds]
1934 | crq->valid = VALID_CMD_RESP_EL;
| ^~
drivers/scsi/ibmvscsi_tgt/ibmvscsi_tgt.c:1875:13: note: while referencing 'msg_hi'
1875 | u64 msg_hi = 0;
| ^~~~~~
There is no change to the resulting binary instructions.
