powerpc/papr_scm: Return the string length from the sysfs show functions
perf_stats_show() and flags_show() build their output with a seq_buf
and return seq_buf_used(), which may include the trailing NUL byte
when the seq_buf has overflowed. Use seq_buf_strlen() instead. As
suggested in review, use it as well for flags_show()'s check whether
any flag was printed.
Build tested ARCH=powerpc ppc64_defconfig with GCC powerpc64-linux-gnu
