mei: lb: fix incorrect type in assignment
Fix the mix between __le32 and integer by casting
the MEI_LB2_CMD constant as __le32 while using it.
Fixes sparse waring:
drivers/misc/mei/mei_lb.c:284:32: sparse: sparse: restricted __le32 degrades to integer
drivers/misc/mei/mei_lb.c:330:40: sparse: sparse: incorrect type in assignment (different base types) @@ expected restricted __le32 [usertype] command_id @@ got int @@
drivers/misc/mei/mei_lb.c:330:40: sparse: expected restricted __le32 [usertype] command_id
drivers/misc/mei/mei_lb.c:330:40: sparse: got int
Fixes: 773a43b8627f ("mei: lb: add late binding version 2")
