clk: npcm7xx: Fix incorrect kfree

[ Upstream commit bbc5080bef4a245106aa8e8d424ba8847ca7c0ca ]

The corresponding allocation is:

> npcm7xx_clk_data = kzalloc(struct_size(npcm7xx_clk_data, hws,
> 			     NPCM7XX_NUM_CLOCKS), GFP_KERNEL);

... so, kfree should be applied to npcm7xx_clk_data, not
npcm7xx_clk_data->hws.
