Charan Teja Kalla 31ca72fa75 mm: compaction: fix compiler warning when CONFIG_COMPACTION=n ...

The below warning is reported when CONFIG_COMPACTION=n:

   mm/compaction.c:56:27: warning: 'HPAGE_FRAG_CHECK_INTERVAL_MSEC' defined but not used [-Wunused-const-variable=]
      56 | static const unsigned int HPAGE_FRAG_CHECK_INTERVAL_MSEC = 500;
         |                           ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Fix it by moving 'HPAGE_FRAG_CHECK_INTERVAL_MSEC' under
CONFIG_COMPACTION defconfig.

Also since this is just a 'static const int' type, use #define for it.
