Subject: soc/tegra: fuse: Clear fuse->clk on driver probe failure

Git-commit: a65a4ea1563218b401a9a638a198e2b8165e967a
Patch-mainline: v5.15-rc1
References: git-fixes

The fuse->clk must be cleared if FUSE driver fails to probe, otherwise
tegra_fuse_readl() will crash. It's unlikely to happen in practice,
nevertheless let's correct it for completeness.
