PM / clk: Fix clock error check in __pm_clk_add()
In the final iteration of commit 245bd6f6 ("PM / clock_ops: Add pm_clk_add_clk()"), a refcount increment was added by Grygorii Strashko. However, the accompanying IS_ERR() check operates on the wrong clock pointer, which is always zero at this point, i.e. not an error. This may lead to a NULL pointer dereference later, when __clk_get() tries to dereference an error pointer. Check the passed clock pointer instead to fix this.
