kill xfs_buf_iostart
xfs_buf_iostart is a "shared" helper for xfs_buf_read_flags, xfs_bawrite, and xfs_bdwrite - except that there isn't much shared code but rather special cases for each caller. So remove this function and move the functionality to the caller. xfs_bawrite and xfs_bdwrite are now big enough to be moved out of line and the xfs_buf_read_flags is moved into a new helper called _xfs_buf_read.
