From: Charan Teja Kalla <quic_charante@xxxxxxxxxxx>
Subject: 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.
