[PATCH 1/2] kallsyms: fix building without printk

[Arnd Bergmann]

Building kallsyms fails without CONFIG_PRINTK due to a missing
declaration:

kernel/kallsyms.c: In function 'kallsyms_show_value':
kernel/kallsyms.c:670:10: error: 'kptr_restrict' undeclared (first use in this function); did you mean 'keyring_restrict'?

This moves the declaration outside of the #ifdef guard, the definition
is already available without CONFIG_PRINTK.

Fixes: c0f3ea158939 ("stop using '%pK' for /proc/kallsyms pointer values")
