clk: clocking-wizard: Fix Oops in clk_wzrd_register_divider()
[ Upstream commit 9c632a6396505a019ea6d12b5ab45e659a542a93 ]
Smatch detected this potential error pointer dereference
clk_wzrd_register_divider(). If devm_clk_hw_register() fails then
it sets "hw" to an error pointer and then dereferences it on the
next line. Return the error directly instead.
