clk: clocking-wizard: Fix Oops in clk_wzrd_register_divider()

Browse source

[ Upstream commit 9c632a6396 ]

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.
