cluster/afr : truncate all sinks files
Problem : During data self-heal of sparse files, sparseness of files is lost. Cause : Earlier, only files with larger ia_size in sinks were being truncated to ia_size of source. This caused checksum mismatch of sparse blocks when ia_size of files in sinks were lesser than ia_size of source file. Leading to unnecessary healing of sparse blocks. As a result of which sparseness of files was lost. Solution : truncate files in all the sinks irrespective of their size with respect to the source file. After this change, checksum won't mismatch for sparse blocks and heal won't be triggered. As a result, sparseness of the files will be preserved. Other fixes in this patch : 1) in afr_does_size_mismatch(), check for mismatch only in sources. Previously, the check was being done for all children in a replica. 2) in __afr_selfheal_data_checksums_match(), check checksum mismatch only for children with valid responses.
