gfs2: Remove use of error flag in journal reads
Conventionally, we use the uptodate bit to signal whether a read
encountered an error or not. Use folio_end_read() to set the uptodate
bit on success. Also use filemap_set_wb_err() to communicate the errno
instead of the more heavy-weight mapping_set_error().
