From: Wang Wensheng <wangwensheng4@xxxxxxxxxx> Subject: mm/sparse: add the missing sparse_buffer_fini() in error branch sparse_buffer_init() and sparse_buffer_fini() should appear in pair, or a WARN issue would be through the next time sparse_buffer_init() runs. Add the missing sparse_buffer_fini() in error branch.
