bpf: Use safer kvmalloc_array() where possible

commit fd58f7df2415ef747782e01f94880fefad1247cf upstream.

The kvmalloc_array() function is safer because it has a check for
integer overflows.  These sizes come from the user and I was not
able to see any bounds checking so an integer overflow seems like a
realistic concern.
