Martynas Pumputis 3084058a72 bpf, selftests: fix handling of sparse CPU allocations 
[ Upstream commit 1bb54c4071f585ebef56ce8fdfe6026fa2cbcddd ]

Previously, bpf_num_possible_cpus() had a bug when calculating a
number of possible CPUs in the case of sparse CPU allocations, as
it was considering only the first range or element of
/sys/devices/system/cpu/possible.

E.g. in the case of "0,2-3" (CPU 1 is not available), the function
returned 1 instead of 3.

This patch fixes the function by making it parse all CPU ranges and
elements.
