Description of PR
fix bug HBASE-26114

When the value is set to a negative number, such as -1, Hmaster cannot start normally. When MOB_COMPACTION_THREADS_MAX is set to 0, mobUtil will set it to 1. But the program does not take into account that it is set to a negative number.

changge
modified
if (maxThreads == 0) {
to
if (maxThreads <= 0) {
to improve the handling mechanism for the user to set hbase.mob.compaction.threads.max as an abnormal value.
