x86: mce: fix type mismatch warning

x86: mce: fix type mismatch warning

[Arnd Bergmann]

The printed symbol is a 64-bit address, so we get a warning when
building this code for 32-bit kernels:

arch/x86/kernel/cpu/mcheck/mce.c: In function '__print_mce':
arch/x86/kernel/cpu/mcheck/mce.c:237:21: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast]

This uses an extra uintptr_t cast to avoid the warning.

Fixes: 7b6061627eb8 ("x86: do not use print_symbol()")

I have no idea where this commit comes from .... It's neither in Linus tree
nor in tip.

Thanks,
