Kaitao Cheng 3a341cb3a2 lib/vsprintf: Make no_hash_pointers take effect early
The no_hash_pointers boot parameter is now handled as an alias for
hash_pointers=never. However, hash_pointers=never only records the
selected mode during early parameter parsing, and no_hash_pointers is
not updated until hash_pointers_finalize() runs later from SLUB init.

This leaves a window during very early boot where %p output is still
hashed even though the user explicitly requested unhashed pointers with
no_hash_pointers or hash_pointers=never.

Set no_hash_pointers as soon as the "never" mode is parsed. The later
hash_pointers_finalize() call still keeps the final policy decision in
one place, but explicit requests to disable pointer hashing now take
effect for early boot users too.
