of: cpu: add check in __of_find_n_match_cpu_property()
In __of_find_n_match_cpu_property(), checking the variable ac for 0 won't
prevent a possible overflow when multiplying it by sizeof(*cell). Besides,
of_read_number() (called in the *for* loop) can't return correct result if
that variable (which equals the #address-cells prop's value) exceeds 2, so
additionally checking for that seems logical...
Found by Linux Verification Center (linuxtesting.org) with the Svace static
analysis tool.
