xfs: kill xfs_buf_geterror()
Most of the callers are just calling ASSERT(!xfs_buf_geterror()) which means they are checking for bp->b_error == 0. If bp is null in this case, we will assert fail, and hence it's no different in result to oopsing because of a null bp. In some cases, errors have already been checked for or the function returning the buffer can't return a buffer with an error, so it's just a redundant assert. Either way, the assert can either be removed. The other two non-assert callers can just test for a buffer and error properly.
