Vignesh Raghavendra 80936d6866 dmaengine: ti: k3-udma: Fix smatch warnings

Smatch reports below warnings [1] wrt dereferencing rm_res when it can
potentially be ERR_PTR(). This is possible when entire range is
allocated to Linux
Fix this case by making sure, there is no deference of rm_res when its
ERR_PTR().
