Bui Quang Minh 063c722dd9 bpf: Check for integer overflow when using roundup_pow_of_two() 
[ Upstream commit 6183f4d3a0 ]

On 32-bit architecture, roundup_pow_of_two() can return 0 when the argument
has upper most bit set due to resulting 1UL << 32. Add a check for this case.

Fixes: d5a3b1f691 ("bpf: introduce BPF_MAP_TYPE_STACK_TRACE")
