dmaengine: xilinx: xdma: Fix regmap init error handling
devm_regmap_init_mmio returns an ERR_PTR() upon error, not NULL.
Fix the error check and also fix the error message. Use the error code
from ERR_PTR() instead of the wrong value in ret.
Fixes: 17ce252266c7 ("dmaengine: xilinx: xdma: Add xilinx xdma driver")
