selftests/mm: compaction_test: fix off by one in check_compaction()
The "initial_nr_hugepages" variable is unsigned long so it takes up to 20
characters to print, plus 1 more character for the NUL terminator.
Unfortunately, this buffer is not quite large enough for the terminator to
fit. Also use snprintf() for a belt and suspenders approach.
