Fix inconsistent IS_ERR and PTR_ERR in sun4i_pwm_probe().

The proper pointers to be passed as arguments are pwm->clk and pwm->bus_clk.

This bug was detected with the help of Coccinelle.

Fixes: b8d74644f34a ("pwm: sun4i: Prefer "mod" clock to unnamed")
Fixes: 5b090b430d75 ("pwm: sun4i: Add an optional probe for bus clock")
