xfs: split xfs_sync_inodes
xfs_sync_inodes is used to write back either file data or inode metadata. In general we always do these separately, except for one fishy case in xfs_fs_put_super that does both. So separate xfs_sync_inodes into separate xfs_sync_data and xfs_sync_attr functions. In xfs_fs_put_super we first call the data sync and then the attr sync as that was the previous order. The moved log force in that path doesn't make a difference because we will force the log again as part of the real unmount process. The filesystem readonly checks are not performed by the new function but instead moved into the callers, given that most callers alredy have it further up in the stack. Also add debug checks that we do not pass in incorrect flags in the new xfs_sync_data and xfs_sync_attr function and fix the one place that did pass in a wrong flag. Also remove a comment mentioning xfs_sync_inodes that has been incorrect for a while because we always take either the iolock or ilock in the sync path these days.
