[PATCH] maple_tree: allow TEST_MAPLE_TREE only when DEBUG_KERNEL is set

[Randy Dunlap]

Prevent a kconfig warning that is caused by TEST_MAPLE_TREE by adding a
"depends on" clause for TEST_MAPLE_TREE since 'select' does not follow
any kconfig dependencies.

WARNING: unmet direct dependencies detected for DEBUG_MAPLE_TREE
  Depends on [n]: DEBUG_KERNEL [=n]
  Selected by [y]:
  - TEST_MAPLE_TREE [=y] && RUNTIME_TESTING_MENU [=y]
