Subject: [PATCH] x86: remove early_res debug output

Commit 08677214e318297 ("x86: Make 64 bit use early_res instead of bootmem 
before slab") introduced early_res replacement for bootmem, but left code 
in __free_pages_memory() which dumps all the ranges that are beeing freed, 
without any additional information, causing some noise in dmesg during 
bootup.

Just remove printing of the ranges, that doesn't provide anything useful 
anyway.

While at it, remove other commented-out KERN_DEBUG messages in the 
NO_BOOTMEM code as well.
