Static analysis tools complain about the -EINVAL error code being
stored in an unsigned variable. Let's change this to match
the clk_get_rate() function which is type unsigned long and returns
zero on error.

v2: In v1 I change the type to int which was wrong. This is a different
approach. CC the freedreno list this time too.
