When phy->ref_clk is NULL PTR_ERR(NULL) will be a success. Fix this by
using -ENOENT when phy->ref_clk is NULL instead.
Fixes: 80090810f5d3 ("phy: qcom: Add QCOM SNPS eUSB2 driver")
Reported-by: Dan Carpenter <dan.carpenter@linaro.org>
Closes: https://lore.kernel.org/all/aDCbeuCTy9zyWJAM@stanley.mountain/
