fs: convert a pile of fsync routines to errseq_t based reporting

This patch converts most of the in-kernel filesystems that do writeback out of the pagecache to report errors using the errseq_t-based infrastructure that was recently added. This allows them to report errors once for each open file description. Most filesystems have a fairly straightforward fsync operation. They call filemap_write_and_wait_range to write back all of the data and wait on it, and then (sometimes) sync out the metadata. For those filesystems this is a straightforward conversion from calling filemap_write_and_wait_range in their fsync operation to calling file_write_and_wait_range.
