[PATCH net-next] qede: allocate enough data for ->arfs_fltr_bmap

[Dan Carpenter]

We've got the number of longs, yes, but we should multiply by
sizeof(long) to get the number of bytes needed.

Btw, this driver use vmalloc() all over the place but kmalloc() is more
appropriate when you're allocating tiny ammounts.
