[PATCH -next] clk: qcom: Fix return value check in apss_ipq6018_probe()

[Wei Yongjun]

In case of error, the function dev_get_regmap() returns NULL pointer
not ERR_PTR(). The IS_ERR() test in the return value check should be
replaced with NULL test.

Fixes: 5e77b4ef1b19 ("clk: qcom: Add ipq6018 apss clock controller")
