net/mlx5: convert miss_list allocation to kvmalloc_array()

Browse Source 
dr_icm_buddy_init_ste_cache() allocates the per-buddy miss_list using
the open-coded kvmalloc(n * sizeof(*p), ...) form.  The neighbouring
allocations in the same function already use the kvcalloc()/
kvzalloc_objs() forms; switch this last one to kvmalloc_array() for
consistency and for the size_mul overflow check that kvmalloc_array()
performs.

The semantics are unchanged: kvmalloc_array() returns a non-zeroed
buffer, just like the previous kvmalloc() call.  Existing callers of
buddy->miss_list initialise each list_head before use.
