lib: sparse: Fix error checking for write_sparse_chunk_raw

Browse Source 
The return value of write_sparse_chunk_raw is unsigned, so the existing
check has no effect. Use IS_ERR_VALUE to detect error instead, which is
what write_sparse_chunk_raw does itself.

Fixes: 62649165cb0 ("lib: sparse: Make CHUNK_TYPE_RAW buffer aligned")
