Commit 036177310b ("clk: mxl: Switch from direct readl/writel based IO
to regmap based IO") introduced code resulting in below warning issued
by the smatch static checker.

  drivers/clk/x86/clk-lgm.c:441 lgm_cgu_probe() warn: passing zero to 'PTR_ERR'

Fix the warning by replacing incorrect IS_ERR_OR_NULL() with IS_ERR().
