cpumask: Omit terminating null byte in cpumap_print_{list,bitmask}_to_buf
The changes in the patch series [1] introduced a terminating null byte
when reading from cpulist or cpumap sysfs files, for example:
$ xxd /sys/devices/system/node/node0/cpulist
00000000: 302d 310a 00 0-1..
Before this change, the output looked as follows:
$ xxd /sys/devices/system/node/node0/cpulist
00000000: 302d 310a 0-1.
Fix this regression by excluding the terminating null byte from the
returned length in cpumap_print_list_to_buf and
cpumap_print_bitmask_to_buf.
