RDMA/rxe: Fix an error handling path in rxe_get_mcg()
The commit in the Fixes tag has shuffled some code.
Now 'mcg_num' is incremented before the kzalloc(). So if the memory
allocation fails, this increment must be undone.
Fixes: 4adc254b7a0d ("RDMA/rxe: Do not call dev_mc_add/del() under a spinlock")
