[PATCH AUTOSEL 4.18 69/92] selftests/android: initialize heap_type to avoid compiling warning

[Sasha Levin]

From: Li Zhijian <lizhijian@xxxxxxxxxxxxxx>

[ Upstream commit cc7c673032fc7427087e74b75f732b43db38a256 ]

Initialize heap_type to ION_HEAP_TYPE_SYSTEM to avoid "used uninitialized"
compiler warning. heap_type gets used after initialization, this change is
to just keep the compiler happy.
