thermal: Fix CPU mask truncation in power limit trace event
num_possible_cpus() counts CPUs, but CPU IDs need not be contiguous.
Using it to size the thermal_power_cpu_limit bitmap can omit CPUs with
higher IDs. For example, possible CPUs 0 and 64 produce an eight-byte
bitmap on a 64-bit system, dropping CPU 64.
Use nr_cpumask_bits for both sizing and copying the bitmap.
