mm,thp: fix smaps THPeligible output alignment
Extract from current /proc/self/smaps output:
Swap: 0 kB
SwapPss: 0 kB
Locked: 0 kB
THPeligible: 0
ProtectionKey: 0
That's not the alignment shown in Documentation/filesystems/proc.rst: it's
an ugly artifact from missing out the %8 other fields are using; but
there's even one selftest which expects it to look that way. Hoping no
other smaps parsers depend on THPeligible to look so ugly, fix these.
