net: ethernet: qlogic: set error code on failure When calling dma_mapping_error(), the value of return variable rc is 0. And when the call returns an unexpected value, rc is not set to a negative errno. Thus, it will return 0 on the error path, and its callers cannot detect the bug. This patch fixes the bug, assigning "-ENOMEM" to err.
