When CONFIG_SCSI_LPFC_DEBUG_FS is unset, uuid's declaration is not
present, resulting in a compiler error:
drivers/scsi/lpfc/lpfc_scsi.c:5595:3: error: use of undeclared
identifier 'uuid'
uuid = lpfc_is_command_vm_io(cmnd);
^
uuid is only used in the if statement so reduce its scope to solve the
build error. Additionally, uuid is a char *, instead of u8 *.
