MIPS: ath79: Fix test for error return of clk_register_fixed_factor().

clk_register_fixed_factor returns an ERR_PTR in case of an error and
should have an IS_ERR check instead of a null check.

The Coccinelle semantic patch used to find this issue is as follows:
@@
expression e;
statement S;
@@

*e = clk_register_fixed_factor(...);
if (!e) S
