powerpc/cacheinfo: Use cpumap_print to print cpumap
Tejun Heo had modified shared_cpu_map_show() to use scnprintf instead
of cpumap_print during support for *pb[l] format. Refer commit
0c118b7bd09a ("powerpc: use %*pb[l] to print bitmaps including
cpumasks and nodemasks").
cpumap_print_to_pagebuf() is a standard function to print cpumap. With
commit 9cf79d115f0d ("bitmap: remove explicit newline handling using
scnprintf format string"), there is no need to print explicit newline
and trailing null character. cpumap_print_to_pagebuf() internally uses
scnprintf(). Hence replace scnprintf() with cpumap_print_to_pagebuf().
Note: shared_cpu_map_show() in drivers/base/cacheinfo.c already uses
cpumap_print_to_pagebuf().
Before this patch:
# cat /sys/devices/system/cpu0/cache/index1/shared_cpu_map

(Notice the extra blank line).
After this patch:
# cat /sys/devices/system/cpu0/cache/index1/shared_cpu_map
