mei: lb: fix incorrect type in assignment

Browse Source 
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
