kallsyms: take advantage of the new '%px' format
The conditional kallsym hex printing used a special fixed-width '%lx' output (KALLSYM_FMT) in preparation for the hashing of %p, but that series ended up adding a %px specifier to help with the conversions. Use it, and avoid the "print pointer as an unsigned long" code. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
