scsi: qla4xxx: Check return value of pci_set_mwi()
pci_set_mwi() has 'warn_unused_result' so the result should be checked.
Fixes the following W=1 kernel build warning(s):
drivers/scsi/qla4xxx/ql4_init.c: In function ‘qla4xxx_pci_config’:
drivers/scsi/qla4xxx/ql4_init.c:664:6: warning: variable ‘status’ set but not used [-Wunused-but-set-variable]
And if 'status' is removed:
drivers/scsi/qla4xxx/ql4_init.c: In function ‘qla4xxx_pci_config’:
drivers/scsi/qla4xxx/ql4_init.c:666:2: warning: ignoring return value of ‘pci_set_mwi’, declared with attribute warn_unused_result [-Wunused-result]
666 | pci_set_mwi(ha->pdev);
