bpf: Use ERR_CAST instead of ERR_PTR(PTR_ERR(...))
Intel linux test robot reported a warning that ERR_CAST can be used
for error pointer casting instead of more-complicated/rarely-used
ERR_PTR(PTR_ERR(...)) style.
There is no functionality change, but still let us replace two such
instances as it improves consistency and readability.
