dm array: fix unreleased btree blocks on closing a faulty array cursor
The cached block pointer in dm_array_cursor might be NULL if it reaches
an unreadable array block, or the array is empty. Therefore,
dm_array_cursor_end() should call dm_btree_cursor_end() unconditionally,
to prevent leaving unreleased btree blocks.
This fix can be verified using the "array_cursor/iterate/empty" test
in dm-unit:
dm-unit run /pdata/array_cursor/iterate/empty --kernel-dir <KERNEL_DIR>
