mm/sparse: add the missing sparse_buffer_fini() in error branch 

[ Upstream commit 2284f47fe9fe2ed2ef619e5474e155cfeeebd569 ]

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.
