hwmon: (peci/cputemp) Fix off-by-one in cputemp_is_visible()
cputemp_is_visible() validates the channel index against
CPUTEMP_CHANNEL_NUMS, but currently uses '>' instead of '>='.
As a result, channel == CPUTEMP_CHANNEL_NUMS is not rejected even though
valid indices are 0 .. CPUTEMP_CHANNEL_NUMS - 1.
Fix the bounds check by using '>=' so invalid channel indices are
rejected before indexing the core bitmap.
